RH.9-10.3: Analyzing a Series of Events and Telling Causes from Mere Sequence
In plain English: RH.9-10.3 is the Common Core literacy standard for history that asks students in grades 9-10 to analyze in detail a series of events described in a text and to decide whether earlier events caused later ones or simply came before them. The key idea is that order alone does not prove cause: the text must show the link. It is usually taught in U.S. History or World History.
Analyze in detail a series of events described in a text; determine whether earlier events caused later ones or simply preceded them.
Common Core State Standards for English Language Arts & Literacy · Domain: Reading Standards for Literacy in History/Social Studies 6-12 · Cluster: Key Ideas and Details · Official standard
Students analyze a series of events in a historical text in detail, event by event, and then test each link: did the earlier event cause the later one, or did it simply precede it? The lesson gives students a short method. First, put the events in order with paragraph numbers. Then, for each pair, look for a causal signal (because, caused by, so ... that, from), and if there is none, ask whether the text's details show how one event led to the next. If neither is true, the text shows only the order, and a reader who writes "because" is adding a claim the text does not make.
The sources are two eyewitness accounts of great city fires. Students model and practice with James B. Stetson's recollections of the San Francisco earthquake and fire of April 1906, which he wrote down in June 1906. For the quiz they read Frank J. Loesch's account of the Chicago fire of October 1871, which he published in 1925. For homework they return to Stetson for the last day of the San Francisco fire, where the earthquake turns up again in an unexpected way. A practice analysis written for this page, with deliberate errors, lets students catch false causes.
Learning Objectives
By the end of this lesson, students will be able to:
Put the events a historical text describes in order, with a paragraph number for each, including events the author reports secondhand
Identify the words that signal a causal link (because, caused by, so ... that, from) and the words that signal only order (then, after, at about this time)
Decide for each pair of events whether the text states a cause, suggests one through its details, or shows only that one event came first
Explain in writing why an earlier event did or did not cause a later one, citing the text, and name a false cause (the post hoc error) when they see it
Prior Knowledge Required
Students should already be comfortable with:
Identifying the key steps in a text's description of a historical process RH.6-8.3
Citing exact words from a source with quotation marks and a paragraph number, and noting the date and origin of the information RH.9-10.1
Basic background: San Francisco was struck by an earthquake on April 18, 1906, and much of the city burned over the next three days; much of Chicago burned on October 8-10, 1871
Start with an everyday case where order and cause come apart.
Warm-Up Prompt
"On Monday a student wore new sneakers and her team won. On Tuesday she wore them again and the team won again. She says the sneakers make the team win. What happened first, and what happened next? Did the first event cause the second? What would you need to know to say that it did?"
Collect answers. Many students will say that the sneakers came first but did not cause the wins. Name the error: treating an event as a cause only because it came first is called post hoc reasoning, from the Latin post hoc, ergo propter hoc, "after this, therefore because of this." Tell students that RH.9-10.3 asks them to trace a series of events in a history text in detail and to decide, for each link, whether the text shows a cause or only an order.
Direct Instruction20 minutes
Part 1: Three kinds of link. Put this table on the board and keep it up all period. The difference between a stated and a suggested cause is whether the author says it or the reader infers it from the details.
Three kinds of link between an earlier event (A) and a later one (B)
Link
What the text does
Words to look for
Stated cause
Says that A produced B
because, caused by, so ... that, from, by means of, as a result
Suggested cause
Gives details that show how A led to B, without a signal word
Details placed side by side; the reader explains the mechanism
Simply preceded
Puts A before B and gives no link, or shows that A ended without producing B
then, next, after, at about this time, the night before
Two cautions. A stated cause is still the author's claim: say who makes it ("Stetson says ..."), and notice whether he saw it or learned it from someone else. And a real cause may exist that the text does not give; if you know it from another source, label it as outside information.
Part 2: Model with Stetson. James B. Stetson lived at 1801 Van Ness Avenue and wrote these recollections in June 1906, two months after the events. Read T1 aloud. Students number the paragraphs and mark every event with a dot in the margin, then circle any causal signal word. Work the four examples below.
1On the morning of April 18, 1906, at 5:13, in my residence, 1801 Van Ness Avenue, I was awakened by a very severe shock of earthquake. The shaking was so violent that it nearly threw me out of bed. It threw down a large bookcase in my chamber, broke the glass front, and smashed two chairs; another bookcase fell across the floor; the chandelier was so violently shaken that I thought it would be broken into pieces. The bric-a-brac was thrown from the mantel and tables, and strewed the floor with broken china and glass. It is said to have lasted fifty-eight seconds, but as nearly as I can estimate the violent part was only about twelve seconds.
2As soon as it was over I got up and went to the window, and saw the air in the street filled with a white dust, which was caused by the falling of masonry from St. Luke's Church on the diagonal corner from my room. I waited for the dust to settle, and I then saw the damage which had been done to Claus Spreckels's house and the church. The chimneys of the Spreckels mansion were gone, the stone balustrade and carved work wrecked. The roof and the points of the gables and ornamental stone work of the church had fallen, covering the sidewalk and lying piled up against the sides of the building to the depth of eight or ten feet.
[...]
3I then went over to the power-house of the California-Street Railroad and found that about seventy feet of the smoke-stack had fallen diagonally across the roof, and about six feet of it into the stable, where were two horses; fortunately it did not touch them, but before they were released they squealed and cried, most piteously. One of them was so badly frightened that he was afterward useless and we turned him out to pasture and he grew lean and absolutely worthless. Things were considerably disturbed, but the engines were apparently uninjured. The watchman was not injured, although surrounded by falling bricks and mortar. I was told that the water supply was stopped, and later learned that it was because the earthquake had broken the water-mains.
4I then started on foot down-town, this was about 7 A. M.; no cars were running on any line. The sidewalks in many places were heaved up, chimneys thrown down, and walls cracked by the earthquake. St. Mary's Cathedral and Grace Church gave no outward sign of being injured; neither did the Fairmont Hotel. I went on California Street, over Nob Hill, and as I got in sight of the business part of the city, I saw as many as ten or twelve fires in the lower part of the city. The wind was light from the northwest, and the smoke ascended in great columns, and the sun through it looked like a large copper disk. When I arrived at California and Montgomery streets the lower part of both sides of California Street seemed to be all on fire. I did not realize that the whole city would be burned. I had a vague idea that it would stop, or be stopped, as fires had been hundreds of times before in this city.

A stated cause (T1, paragraph 2)
"I got up and went to the window, and saw the air in the street filled with a white dust, which was caused by the falling of masonry from St. Luke's Church."
Result: Stated cause. The signal "caused by" links the falling masonry (A) to the dust (B). Stetson also shows that the masonry fell in the earthquake: he looks out "as soon as it was over" and sees "the damage which had been done." The chain is earthquake, falling masonry, dust.
A stated cause learned secondhand (T1, paragraph 3)
"I was told that the water supply was stopped, and later learned that it was because the earthquake had broken the water-mains."
Result: Stated cause, with the signal "because." Stetson did not see the broken mains: he was "told" the water had stopped and "later learned" the reason. An accurate analysis keeps that source: "Stetson reports that he later learned the earthquake had broken the water-mains."
Only an order (T1, paragraph 4)
"I saw as many as ten or twelve fires in the lower part of the city."
Result: Simply preceded, as far as T1 goes. The fires come after the earthquake in the text, but T1 gives no signal word and no detail about how any fire began. A reader who writes "the earthquake started the fires" is using outside information, and must say so. Order in the text is not a causal claim.
A model analysis of T1 (78 words)
Task: in 80 words or fewer, analyze the chain of events in T1 and say which links the text shows as causes.
Result: Stetson's account ties two chains to the earthquake. First, the shock brings down stone from St. Luke's Church, and the falling masonry fills the street with dust, a link he states with "caused by" (paragraph 2). Second, the water supply stops, and he "later learned" the cause was broken water-mains (paragraph 3). The fires differ: he sees them about two hours after the shock, but T1 never says what started them, so here the earthquake only precedes them.
Show Diagram 1. Each row is one chain from T1; the solid arrows are links the text states or clearly shows, and the dashed arrows are links where the text gives only the order. Then show Diagram 2 and walk through its questions with the example of the fires.
Guided Practice15 minutes
Read T2 together. It is the afternoon of the next day, April 19, and the fire is approaching Stetson's own street. Pairs list the events of paragraph 2 in order with the times Stetson gives (3:00, 3:30, 4:00-4:30), then label each link with Diagram 2. Stop after paragraph 2 and ask: Which link does Stetson state with the word "caused"? Is it something he saw, or his judgment?
1As it approached Van Ness it did not burn north of Washington Street. The wind being northwest, and Van Ness Avenue 125 feet in width, I felt sure the fire would not cross.
[...]
2At 3 o'clock the soldiers drove the people north on Van Ness and west up to Franklin Street, saying that they were going to dynamite the east side of Van Ness. From my window I watched the movements of the fire-fighters and dynamiters. They first set fire to every house on the east side of Van Ness Avenue between Washington and Bush streets, and by 3:30 nearly every one was on fire. Their method was this: A soldier would, with a vessel like a fruit-dish in his hand, containing some inflammable stuff, enter the house, climb to the second floor, go to the front window, open it, pull down the shade and curtain, and set fire to the contents of his dish. In a short time the shades and curtain would be in a blaze. When the fire started slowly, they would throw bricks and stones up to the windows and break the glass to give it draught. It took about 20 minutes for a building to get well on fire. From 4 to 4:30 St. Luke's and the Presbyterian Church and all the houses on Van Ness Avenue from Bush to Washington were on fire. At about this time they began dynamiting. Then they started backfiring, and, as the line, of fire was at Polk Street, the idea was to meet the flames and not allow them to cross Van Ness Avenue. This was a great mistake, as it caused the whole of the blocks between those streets to be on fire at once, which made an intense heat, while if allowed to approach Van Ness from Polk Street the heat would have been much less, and would not have ignited the west side of Van Ness. The explosions of dynamite were felt fearfully in my house; those within two blocks would jar and shake the house violently, breaking the windows, and at the same time setting off the burglar alarm. As the windows would break it tore the shades and curtains, covered the floor with glass, and cracked the walls. After it was over I found that it had demolished in my house twelve plates and fifty-four sheets of glass, each measuring about thirty by fifty inches.
[...]
3Another tier of blocks, from Leavenworth to Van Ness, between Jackson and Pacific, had taken fire. This was about 10:15 P. M.. At 11:15 it had got to Van Ness, and Bothin's house, which was at the corner of Van Ness and Jackson, was fully on fire, but although it was entirely consumed, the fire did not cross to the west side of Van Ness. The wind during all the day and evening was steady from the northwest,--not a very strong wind, but it helped protect the west side of Van Ness.
James B. Stetson, San Francisco During the Eventful Days of April, 1906 (excerpt: dynamite on Van Ness Avenue, April 19) (1906). Public domain (published 1906). Source text.
Teacher model for the pair work: The soldiers set fire to the houses on the east side of Van Ness, and then, "at about this time," the dynamiting and backfiring begin; the text gives the order of these steps, and their purpose ("to meet the flames"), but not a cause of one by the other. Stetson states a cause and judges it: the backfiring "caused the whole of the blocks between those streets to be on fire at once," which he calls "a great mistake." He saw the fire and the heat; the claim that the west side would otherwise have been safe is his judgment about what might have happened. The explosions breaking his windows is a cause he felt in his own house, and he counts the result: "fifty-four sheets of glass."
Ask pairs to compare paragraphs 1 and 3. In paragraph 1 Stetson expects the width of the avenue and the wind to stop the fire; paragraph 3 reports that later that night the fire did not cross. Does paragraph 3 prove his explanation? It says the wind "helped protect" the west side, a stated cause, but T2 cannot show what would have happened with a different wind.
Practice analysis for Activity 2. The passage below was written for this page and contains deliberate errors. Pairs will test it against T1 and T2.
Stetson's account shows a clear chain of causes on the morning of April 18. The earthquake threw down his bookcase, and because the bookcase fell, the chandelier shook so violently. The falling masonry from St. Luke's Church caused the white dust in the street. Because the water supply stopped, the earthquake broke the water-mains.
The earthquake then started the ten or twelve fires that Stetson saw downtown, as T1 explains. Because the wind was light from the northwest, the smoke rose in great columns.
In the afternoon, soldiers set fire to the houses on the east side of Van Ness Avenue, and then they began dynamiting, so setting the houses on fire caused the dynamiting. Finally, the dynamite explosions broke the windows in Stetson's house.

Independent Practice15-20 minutes
Students read two excerpts from Frank J. Loesch's account of the Chicago fire of October 1871. Loesch was a young bookkeeper for the Western Union Telegraph Company at the time and later a Chicago lawyer; he published this account in 1925, 54 years after the fire. Students mark each event and circle each causal signal, then take the quiz, which uses T3 and T5 along with T1.
1The summer of 1871 was an intensely hot one. No rain had fallen in the Lake region for about three months prior to October 8th. Great forest fires with large loss of life were taking place in the then heavily pine-forested regions of Central and Northern Michigan and Wisconsin. I recall our excitement on Saturday and Sunday, October 7th and 8th, on reading in the morning papers stories of the destruction of forests and villages, with the loss of many lives, about Sturgeon Bay and other places in Wisconsin and Michigan.
2As is generally known, the residential portion of Chicago was almost wholly constructed of wood. Brick and limestone structures were largely confined to the South Side business district.
[...]
3The sidewalks, except in the South Side business district, where limestone flags predominated, were entirely of pine or hemlock planking and many of the streets were raised on wooden supports from four to ten feet above the natural surface to meet the street grades which had by that much been raised above the natural surface. It can be seen what added fuel to a general fire was made by such construction of sidewalks and street pavements. The raised portions of the streets were sustained by heavy stone retaining walls on each side.
[...]
4Before midnight of Saturday, October seventh, our household of about thirty boarders was aroused by cries of “Fire!” The sky was red from a southwesterly blaze. A number of the young men, including myself, started for the scene of it and were stopped on the east side of the Madison Street bridge. From there we saw the destruction of the then Union Railroad Station, a frame structure, located on the East Side of Canal Street, opposite Monroe Street. South of Adams Street to Van Buren Street were located planing mills and lumber yards. The fire was fierce and spectacular with such material to feed upon, but there was no wind and the fire exhausted itself without crossing the South Branch of the river. That was the night before the beginning of the great fire. It brought directly home to us all the fire hazard the city was exposed to and little else was talked of on that Sunday. Everything was as dry as tinder from the long drouth and great summer heat.
[...]
5As churchgoers were coming out of their places of worship on Sunday evening, fire bells were ringing furiously and a rapidly increasing red glare towards the Southwest Side indicated that another fire had broken out. A strong hot wind had been blowing from the southwest during the day and it seemed to have gained in strength at this time.
[...]
6Some time after leaving Monroe and Franklin Streets there was a loud explosion. I learned from the crowd making its way to the tunnel that it was the explosion of the gas works. Gas lights had gone out everywhere and the escaping gas had doubtless hastened the action of the fire in many buildings. At any rate the tunnel was dark.

1Here LeRow revived and we parted, he to go north, I to go into the Telegraph Company’s office to learn if I could be of service. Some three or four of my fellow clerks were there, besides the manager. Some one had opened the vault door, into which we put all the books of account that were about, the men having worked on them that day. Unfortunately the chief bookkeeper had been working all day in a private room on the fourth floor, on his September accounts and had left many of the books up there for the night. They were, of course, lost. I saw the manager place a lot of gold coins into a small portable office safe at his desk. It was suggested to him that we move the safe into the large vault but he declined to have it done as being unnecessary. After the fire the stack of vaults in that building was found upright amidst the debris of the rest of the building, the contents of each vault being intact, but the manager’s safe had been melted down and after diligent search amidst the ruins there was found only a little trickle of gold in the shape of a thin vein over some bricks.
2All salvage work in our office was being done by the light of the flames. The building opposite on Washington Street was ablaze and the roof of our building was burning. The telegraph operators had abandoned their instruments on the upper floors and were running down the stairway as I hurried into La Salle Street and ran north to Randolph Street.
[...]
3I stopped for a few moments at the north corner of Randolph and La Salle Streets to look about me. All the buildings south on La Salle Street as far as I could see, south of Washington Street, were ablaze. So were some north of it. My particular attention was, however, called to the Court House and City Hall. The former had for its center building a brown stone structure surmounted by a cupola in which was hung a large bell. The interior of the building was burning and the flames being carried up through the open space had set the bell to ringing. Above all the sounds of the roaring fire, the wind and the excited shouts of a moving mass of people the bell whirled on its frame and over its stanchions, ringing out with a weirdness and a despairing clangorous volume, as though it were possessed of sense and were agonizing in its struggle against destruction. For many years thereafter the memory of its clangor often awoke me at night to recall the scene.
4The east and west wings of the Court House were constructed of Joliet limestone--the west wing being the City Hall. I watched for some moments, with a fascination which only the growing danger to myself drew me away from, the effect of the fire upon the city hall. The strong southwest wind was driving the heat in sheets of flame from the hundreds of burning buildings to the west of it, upon the southwest corner of the building, with such terrific effect that the limestone was melting and was running down the face of the building with first a slow then an accelerating movement as if it were a thin white paste.

Closure5-10 minutes
Exit ticket: On an index card, write one pair of events from T1 or T2 that the text links as cause and effect, with the signal word, and one pair where the earlier event simply preceded the later one. Give paragraph numbers for both.
Teacher note on the sources and their language: The passages are quoted exactly as published, including older spellings ("drouth" for drought), the stray comma in "the line, of fire," and Loesch's use of "melting" for the limestone of the City Hall. Limestone does not melt in a building fire: strong heat cracks and spalls its face and slowly turns the stone into quicklime, a soft white powder that crumbles away, and that may be what Loesch saw. Stetson writes as a property owner tied to the California-Street Railroad, whose power-house he checks in T1; his judgment that the backfiring was a mistake is one resident's view. Loesch wrote more than fifty years after the fire, so his account depends on long memory; and he reports some things he did not see himself. Neither excerpt contains slurs. Remind students that a cause an author states is still that author's claim.
Homework passage. Stetson's account of April 20, the last day of the fire, used for the homework problems.
1About noon on the 20th the blocks between Pacific and Filbert were on fire at Jones Street, and the fire was again threatening Van Ness Avenue, but several engines were pumping, from one to another, saltwater from Black Point and had a stream on the west side of Van Ness until it was saved.
2While the fire was threatening, I went up to my daughter's (Mrs. Oxnard's) and told the servants to get things ready to take out. I would go back home, and if it crossed Van Ness I would return, but if I did not return in fifteen minutes they might consider the danger over. It did not cross. While this pumping was going on, and when the fire had approached the east side of Van Ness Avenue, one of the engines in the line suddenly stopped. This was a critical moment, but the firemen were equal to the emergency, and they uncoupled the engine which was playing on the houses, and remembering that the earthquake had disrupted and choked up the sewer, thereby damming up the outlet, and in fact creating a cistern, they put the suction down the manhole and continued playing on the fire, and saved the buildings on the north side. I tried to get the names of the foreman and men who had the presence of mind and cool judgment, but was unable to do so. This ended the conflagration; but for three nights after there were fires from smouldering timbers and slow-burning debris, sufficient to light up my room so that I could see to read. I was still in fear of a fire breaking out in the unburnt district west of Van Ness Avenue, and as there was no water in the pipes we would be as helpless as ever. This gave much anxiety during the two weeks following the calamity.

Differentiation Strategies
For Struggling Students
Give an event chart with the paragraph numbers already filled in, so students only write the event and choose one of three link labels
Provide a signal word bank on a card: because, caused by, so ... that, from, as a result (cause); then, next, after, at about this time (order)
Gloss older words in the margin: bric-a-brac, masonry, water-mains, backfiring, draught, drouth, tinder, clangor, stanchions
For Advanced Students
Read the rest of Stetson's recollections and find a place where he says an event would have happened if something else had not; explain what kind of evidence a claim like that needs
Compare T1 with T3: Stetson writes two months after the events and Loesch fifty-four years after. Explain how the gap might affect which causes each one states
Find a causal claim in T3 or T5 that Loesch could not have seen himself, and explain how he might have come to know it
Assessment Guidance
What to Look For
Strong work lists events in the text's order with paragraph numbers, and for each link names the kind of connection with the words that decide it. Watch for four errors: writing "because" where the text has only "then" or "and"; reversing a cause and its effect; treating two effects of the same cause as causes of each other; and bringing in a cause from outside knowledge without labeling it. Strong answers also say whose claim a cause is and whether the author saw it or was told.

Event Cards and Link Cards
20 minGroups of 3-4
Groups receive eight event cards from T1 and T2 in scrambled order and six link cards: three that read CAUSED and three that read THEN. They put the events in order, then place link cards between chosen pairs and defend each one with the words of the text.
The Eight Event Cards (teacher copy, in the correct order)
The earthquake shakes Stetson's house at 5:13 A.M. (T1, paragraph 1)
Masonry falls from St. Luke's Church, and white dust fills the street (T1, paragraph 2)
The water supply stops (T1, paragraph 3)
Stetson sees ten or twelve fires in the lower part of the city (T1, paragraph 4)
Soldiers drive people away and set fire to the houses on the east side of Van Ness (T2, paragraph 2)
The dynamiting and backfiring begin (T2, paragraph 2)
Dynamite explosions break the windows in Stetson's house (T2, paragraph 2)
The fire does not cross to the west side of Van Ness (T2, paragraph 3)
Link Key for the Teacher
CAUSED, card 1 to card 3: "because the earthquake had broken the water-mains" (T1, paragraph 3). The two cards are not next to each other, which is the point: a cause need not come just before its effect.
CAUSED, card 1 to card 2: the dust "was caused by the falling of masonry," and Stetson sees the damage right after the shock (T1, paragraph 2).
CAUSED, card 6 to card 7: the explosions shook the house, "breaking the windows" (T2, paragraph 2).
THEN, card 1 to card 4: T1 gives no cause for the fires.
THEN, card 5 to card 6: "At about this time they began dynamiting" gives time, not cause.
THEN, card 6 to card 8: Stetson does not credit the backfiring with saving the west side; he credits the wind, which "helped protect" it.
Procedure
Cut the cards apart and shuffle them before handing them out
Put the eight event cards in order and write the text and paragraph number on each
Place all six link cards between pairs of events; a link may join cards that are not next to each other
For each link card, write the words from the text that justify it on a sticky note
Discussion Questions
Card 1 is linked by a stated cause to card 3 and only by order to card 4. What is the difference in the text?
Did any group put CAUSED between cards 5 and 6? What words in T2 would they need, and are they there?
Stetson calls the backfiring "a great mistake." Which card does that judgment concern, and is it something he saw or something he concluded?
Variation for a Shorter Class
Give groups cards 1-4 only, with two CAUSED cards and one THEN card, and have them justify each link in one sentence.
2
False Cause Detective
15-20 minPairs
Pairs test the practice analysis T6 (in the Guided Practice phase) against T1 and T2. It contains five deliberate causal errors. Pairs find each one, name the kind of error, and rewrite the analysis so that every causal claim can be traced to the text.
Procedure
Number the sentences of T6
Underline every causal claim (because, caused, started, so ... caused)
For each one, write supported or error, with the paragraph of T1 or T2 that decides it
Name each error: reversed cause, two effects linked to each other, outside cause, "and" read as "because," or order read as cause
Rewrite T6 in 120 words or fewer so that every causal claim is supported
Answer Key for the Teacher
Two effects linked to each other: the earthquake threw down the bookcase and shook the chandelier; the bookcase did not shake the chandelier (T1, paragraph 1).
Reversed cause: the earthquake broke the water-mains, and that is why the water supply stopped (T1, paragraph 3), not the other way around.
Outside cause: T1 does not explain how the fires started, so "as T1 explains" is false (T1, paragraph 4).
"And" read as "because": T1 says the wind was light "and" the smoke rose in great columns; it states no link between them (T1, paragraph 4).
Order read as cause: in T2 the burning comes first and the dynamiting "at about this time"; the text gives no cause of one by the other (T2, paragraph 2).
Two claims in T6 are supported: the falling masonry caused the dust (T1, paragraph 2), and the explosions broke Stetson's windows (T2, paragraph 2). The opening sentence is an overstatement once the errors are removed, since some of the links are only order.
Discussion Questions
Which error would be hardest to catch without rereading the text? Why?
Is it ever fair to write "the earthquake started the fires" in an analysis of T1? What would you have to add?
3
Timeline or Cause Map?
15 minPairs, then whole class
Pairs draw two pictures of T2 on chart paper: a timeline that shows only the order of events with Stetson's times, and a cause map that shows only the links the text states. Comparing the two shows which events belong to the sequence but not to any cause.
Procedure
On the left half, draw a timeline of T2 with every time Stetson gives (3:00, 3:30, 4:00-4:30, 10:15, 11:15)
On the right half, draw a cause map: an arrow only where T2 states or clearly shows a cause, with the signal words on the arrow
Circle every event that appears on the timeline but has no arrow on the cause map
Post the charts and do a gallery walk; each pair adds one sticky note to another pair's cause map
Discussion Questions
Which events are on your timeline but not on your cause map? Why are they still worth keeping in an analysis?
T2 gives times from 3:00 to 11:15. Does a long gap between two events make a causal link less likely, more likely, or neither?
Modification for English Learners
Provide the timeline already drawn with the times filled in, and a strip of arrow labels (caused, broke, helped protect, then, at about this time) to place on the charts.

Diagrams & Visual Aids
2 diagrams
Diagram 1: Three Chains in T1, Caused or Only Followed
Three chains of events that begin with the earthquake in Stetson's account (T1). In the first two rows the text states the link ("caused by," "because"). In the third, the fires come after the earthquake, but T1 gives no link, so the text shows only the order.
Diagram 2: Did the Earlier Event Cause the Later One?
Two questions sort any pair of events into a stated cause, a suggested cause or a simple sequence. Ask them in order, and cite the words that decide each answer.

RH.9-10.3 Homework: The Last Stand at Van Ness Avenue, April 20, 1906
Directions: Use T4, Stetson's account of April 20, printed in the Closure phase of the lesson plan; Problems 2 and 6 also use T1. Quote exact words where a problem asks for them, and give the paragraph number. Answer Problems 1-5 in 2-5 sentences each; Problem 6 is a paragraph.
Part 1: The Series of Events (Problems 1-3)
List the events of T4 paragraph 2, from the moment one engine stops to the saving of the buildings, in the order they happen, in four or five short sentences.
The firemen's solution in T4 paragraph 2 depends on an event from two days earlier. Quote the words that name that earlier event, and explain the chain from it to the saving of the buildings.
In T4 paragraph 1, what does Stetson say saved Van Ness Avenue at noon on the 20th? Quote the words, and say whether this is a stated cause, a suggested cause or only an order.
Part 2: Caused or Simply Preceded? (Problems 4-6)
In T4 paragraph 2, Stetson visits his daughter's house while the fire is threatening, and then "It did not cross." Did his visit have anything to do with the fire not crossing? Explain, using the words of the text.
Stetson writes, "This ended the conflagration." What does "This" refer to? Then quote the words that show the fire was not fully over, and explain how both statements can be true.
Write a paragraph of 120-150 words that analyzes how the earthquake affected the firefighting, using T1 paragraph 3 and T4 paragraph 2. Show one way it hurt and one way it helped, say for each link whether the text states it, and cite paragraph numbers.

Question 1 of 20 · Multiple Choice
According to paragraph 1 of T3, how long had the Lake region gone without rain before October 8, 1871?
Answer: B
Paragraph 1: "No rain had fallen in the Lake region for about three months prior to October 8th." Choice A and choice C misread the number. Choice D invents spring floods that T3 never mentions.
Question 2 of 20 · Multiple Choice
Paragraph 1 of T3 mentions great forest fires in Michigan and Wisconsin. What does T3 show about how they relate to the Chicago fire?
Answer: C
Loesch read about the forest fires in the papers on October 7 and 8, the same dry weeks; he gives no link between those fires and Chicago's. Choice A is a false cause built on order. Choice B reverses the order: the forest fires were already in the papers. Choice D has no support; paragraph 4 names no cause for the Saturday fire.
Question 3 of 20 · Multiple Choice
Which words in paragraph 3 of T3 state that the city's wooden sidewalks and streets made the fire worse?
Answer: A
Only choice A makes a causal claim: the construction "added fuel." Choice B and choice C describe how the streets were built but draw no link to the fire; choice C is the condition that choice A then explains. Choice D names the one area where the sidewalks were stone.
Question 4 of 20 · Multiple Choice
According to paragraph 4 of T3, why did the Saturday night fire not cross the South Branch of the river?
Answer: D
Paragraph 4: "there was no wind and the fire exhausted itself without crossing the South Branch of the river." Choice A misreads the bridge: Loesch and the other young men "were stopped" there, not the fire. Choice B contradicts the drought in paragraphs 1 and 4. Choice C has no support.
Question 5 of 20 · Multiple Choice
Which statement best describes how T3 connects the Saturday night fire to the great fire that began on Sunday?
Answer: B
Loesch calls the Saturday fire "the night before the beginning of the great fire" and says it "exhausted itself"; paragraph 5 says that on Sunday "another fire had broken out." That is an order, not a cause. Choice A invents embers. Choice C contradicts "another fire." Choice D may sound reasonable, but T3 does not say it; a reader who brings in such a claim must label it as outside information.
Question 6 of 20 · Multiple Choice
According to paragraph 4 of T3, what did the Saturday night fire cause?
Answer: A
Paragraph 4: "It brought directly home to us all the fire hazard the city was exposed to and little else was talked of on that Sunday." That is the one effect T3 gives the Saturday fire. Choice B confuses order with cause: the wind is reported on Sunday, with no link to Saturday. Choice C has no support in T3. Choice D gives the Saturday fire an effect that T3 assigns to the drought: the city was dry "from the long drouth."
Question 7 of 20 · Multiple Choice
In paragraph 4 of T3, Loesch writes that the Saturday fire "was fierce and spectacular with such material to feed upon." What is "such material"?
Answer: C
The sentence before names the fuel: "South of Adams Street to Van Buren Street were located planing mills and lumber yards." The phrase "with such material to feed upon" is a stated cause of the fire's fierceness. Choice A refers to the gas works, which appear only on Sunday night (paragraph 6). Choice B is from paragraph 3, which describes the city in general. Choice D moves the fuel of the forest fires in paragraph 1 to Chicago.
Question 8 of 20 · Multiple Choice
How does Loesch present the link between the escaping gas and the fire in paragraph 6 of T3?
Answer: D
Loesch writes that the escaping gas "had doubtless hastened the action of the fire in many buildings." He was on his way to the tunnel and reports no building he saw; "doubtless" signals a cause he infers. Choice A overstates what he saw. Choice B confuses the link with the report of the explosion, which he accepts from the crowd. Choice C is wrong: the gas "hastened" a fire already burning.
Question 9 of 20 · Multiple Choice
In paragraph 6 of T3, how does Loesch know that the loud explosion came from the gas works?
Answer: A
"I learned from the crowd making its way to the tunnel that it was the explosion of the gas works." This is a secondhand report, which an analysis should keep. Choice B invents an eyewitness view. Choice C and choice D have no support in T3.
Question 10 of 20 · Multiple Choice
Which list gives events in the order T3 presents them?
Answer: B
The drought is in paragraph 1, the Saturday fire in paragraph 4, the fire bells "on Sunday evening" in paragraph 5, and the explosion in paragraph 6. Choice A puts the Saturday fire before the months of drought. Choice C starts with Sunday. Choice D moves the explosion to the start.
Question 11 of 20 · Multiple Choice
A student writes: "Because churchgoers were coming out of their churches on Sunday evening, the fire bells began to ring." What is wrong with this sentence?
Answer: D
Paragraph 5 says "As churchgoers were coming out ... fire bells were ringing furiously": "as" here means "while," and the bells signal a fire, not the end of services; T3 gives no link between the two. Choice A misreads "as" as "because." Choice B contradicts "on Sunday evening." Choice C swaps in a different false cause instead of fixing the error.
Question 12 of 20 · Multiple Choice
According to paragraph 1 of T5, why were the books in the fourth-floor room lost?
Answer: C
The clerks put "all the books of account that were about" into the vault, but the chief bookkeeper "had left many of the books up there for the night. They were, of course, lost." Choice A contradicts "Some one had opened the vault door." Choice B confuses the books with the manager's safe. Choice D misreads paragraph 2, where the operators abandon their instruments.
Question 13 of 20 · Multiple Choice
What does paragraph 1 of T5 suggest caused the loss of the manager's gold coins?
Answer: A
T5 gives no "because," but it sets the details side by side: the manager "declined to have it done as being unnecessary," the vaults were found "intact," and the safe "had been melted down." That is a suggested cause. Choice B reverses what happened to the vaults. Choice C confuses the coins with the books. Choice D is a false cause taken from T3.
Question 14 of 20 · Multiple Choice
According to paragraph 3 of T5, what set the Court House bell ringing?
Answer: B
"The interior of the building was burning and the flames being carried up through the open space had set the bell to ringing": a stated cause. Choice A has no support. Choice C uses the wind, which in paragraph 4 drives heat onto the City Hall, not the bell. Choice D is a false cause from T3, where the explosion is a separate event.
Question 15 of 20 · Short Answer
In paragraph 4 of T5, what does Loesch say caused the limestone of the City Hall to "melt"? Trace the chain in at least two links, and quote the signal words.
Model answer: The chain starts with "the hundreds of burning buildings to the west of it." The strong southwest wind was "driving the heat in sheets of flame" from those buildings onto the southwest corner of the City Hall, "with such terrific effect that the limestone was melting." The signal "with such terrific effect that" states the cause. Rubric: full credit for both links (burning buildings and wind-driven heat) and the quoted signal words; partial credit for one link or no quotation.
Question 16 of 20 · Short Answer
In paragraph 6 of T3, trace the chain that runs from the explosion to the dark tunnel. Which link does Loesch state, and which does the reader have to infer?
Model answer: The events are: a loud explosion, which Loesch learned was the gas works; "Gas lights had gone out everywhere"; and "At any rate the tunnel was dark." Loesch never writes that the explosion put out the lights or that the lights going out made the tunnel dark; the order and the details suggest those links, and the reader infers them. The words "At any rate" show that he is setting the cause aside and reporting the result. Rubric: full credit for the three events in order and a correct statement of what is inferred; partial credit for the order only.
Question 17 of 20 · Short Answer
In T1 paragraph 4, Stetson expected the fire "would stop, or be stopped, as fires had been hundreds of times before." In T3 paragraph 4, the Saturday fire in Chicago stopped too. Explain why earlier fires that stopped do not show that a later fire will stop.
Model answer: Earlier fires only came before the later one; they did not cause it to stop. Whether a fire stops depends on the conditions at that time. Loesch's Saturday fire stopped because "there was no wind and the fire exhausted itself," but the next evening "A strong hot wind had been blowing from the southwest" (T3, paragraph 5). In San Francisco the conditions had changed as well: the water supply had stopped (T1, paragraph 3). Rubric: full credit for the point that order is not cause and one condition from either text; partial credit for the general point without evidence.
Question 18 of 20 · Short Answer
Choose four events from T3, in order, with paragraph numbers. Label each of the three links as a stated cause, a suggested cause or only an order, and give the words that decide each label.
Model answer (one of several): (1) No rain for about three months (paragraph 1). Link: stated cause, "Everything was as dry as tinder from the long drouth" (paragraph 4). (2) Everything dry as tinder (paragraph 4). Link: only an order; T3 says nothing about how the Sunday fire began. (3) "another fire had broken out" on Sunday evening (paragraph 5). Link: only an order; the text reports the explosion later that night without tying it to the start of the fire. (4) The gas works explode (paragraph 6). Rubric: full credit for four events in T3's order with paragraph numbers and three correct labels with deciding words; partial credit for correct order with one mislabeled link.
Question 19 of 20 · Short Answer
A classmate says: "The long drought caused the Great Chicago Fire." Using T3, explain what the text supports in this claim and what it does not.
Model answer: T3 supports the drought as a condition: "No rain had fallen ... for about three months," and "Everything was as dry as tinder from the long drouth" (paragraphs 1 and 4). A dry city burns more easily, and the wooden construction "added fuel" (paragraph 3). But T3 never says what started the fire on Sunday evening; it says only that "another fire had broken out" (paragraph 5). The drought helped the fire spread, but T3 does not show it as the event that began it. Rubric: full credit for separating a condition from the starting event, with two quotations; partial credit for one side only.
Question 20 of 20 · Short Answer
T5 describes one effect of the fire that lasted for many years. Identify it, quote it, and explain whether T5 states its cause.
Model answer: "For many years thereafter the memory of its clangor often awoke me at night to recall the scene" (paragraph 3). T5 states the cause: the memory of the bell's sound woke him. The chain runs from the burning interior, to the flames that "set the bell to ringing," to the sound Loesch heard, to the memory that woke him for years. Rubric: full credit for the quotation, the stated cause and at least one earlier link; partial credit for the quotation only.

Frequently Asked Questions
10 Questions
What does RH.9-10.3 mean?
RH.9-10.3 asks students in grades 9-10 to analyze in detail a series of events described in a history text and to determine whether the earlier events caused the later ones or simply came before them. "RH" stands for Reading in History/Social Studies. In practice, students put the events in order with evidence, then test each link against the words of the text.
How is RH.9-10.3 different from RH.11-12.3?
RH.9-10.3 works inside one series of events and asks whether each earlier event caused a later one. RH.11-12.3 starts from competing explanations of an action or event, asks which one best accords with the textual evidence, and asks students to acknowledge where the text leaves matters uncertain. The 9-10 skill of telling cause from sequence is a building block for weighing explanations in 11-12.
What is the difference between an event that caused another and one that simply preceded it?
An event causes another when it produces it; it simply precedes it when it only comes first. A text shows a cause with a signal (because, caused by, so ... that) or with details that show how one event led to the next. If the text gives only the order (then, next, the night before), the reader cannot claim a cause from that text alone.
What is the post hoc fallacy?
It is the error of treating an event as a cause only because it came first. The name comes from the Latin post hoc, ergo propter hoc, "after this, therefore because of this." History texts invite it because they tell events in time order, so every earlier event can look like a cause of the next.
What words signal cause and effect in a historical text?
Common signals are because, since, caused, caused by, so ... that, from, as a result, therefore and by means of. Watch for look-alikes: "as" can mean "while" ("As the band played, the rain began"), and "and" joins events without linking them. A signal word shows the author's claim, which the reader can still question.
Can a text show a cause without saying "because"?
Yes. An author can place details side by side so that the link is clear, as in a report that a bridge washed out on Monday and that on Tuesday the town's market had no fresh fish. Call this a suggested cause, cite the details, and say that the link is the reader's inference.
Which class teaches RH.9-10.3?
RH.9-10.3 is a literacy standard for history and social studies, so it is usually taught in U.S. History or World History in grades 9-10, often alongside English classes that teach RI.9-10.3. It fits any unit built on primary sources that describe events in order, such as disasters, battles, elections or reform movements.
Why use eyewitness accounts of the San Francisco and Chicago fires?
Both are short first-person accounts in the public domain in which events pile up quickly and the writers sometimes state causes and sometimes only report order. Stetson wrote two months after the 1906 earthquake and fire; Loesch wrote fifty-four years after the 1871 fire. Together they let students test causal links in two different cities and with two different gaps between event and account.
How can teachers assess RH.9-10.3?
A good assessment gives students an unfamiliar passage and asks them to order the events, label each link as a stated cause, a suggested cause or only an order, and defend each label with quoted words. Short written analyses and false-cause claims to correct, like the ones in this lesson's quiz, show whether students can do this without the teacher's prompts.
How do I help students who write "because" for every pair of events?
Make them find the evidence before they write the claim. Give each pair of events two cards, CAUSED and THEN, and require a quoted signal word or detail before the CAUSED card can be used. Students soon see that many links in a narrative are only order, and their analyses become more exact.
