Classroom activity Grade 4 English Language Arts
Paragraph Build at the Plumridge Booster Pump Station
Groups of four sort twelve sentence strips about a fictional pump station into two grouped paragraphs, discard two strays, and write headings and closing sentences.
Objectives
- Students will group related sentences into two paragraphs about one topic.
- Students will identify sentences that do not support either paragraph and explain why.
- Students will write a heading and a concluding sentence for each grouped paragraph.
Vocabulary
Key words: topic sentence, detail, heading, booster pump, gauge
Teacher overview
Groups of four open an envelope of twelve sentence strips about a fictional booster pump station in the town of Plumridge and physically build two paragraphs out of them, one about what the station does and one about how its crew keeps it working. Two strips belong to neither paragraph, so the sorting cannot be finished by simply dealing out every card. Fourth graders often treat a paragraph as any six sentences on roughly the same subject, which is why the two strays here are true statements about Plumridge that still support neither idea. Moving the strips by hand makes the grouping decision visible before anyone writes.
Activity Directions
- Before class, print the Student Handout, cut one set of twelve strips per group, and put each set in an envelope. Groups of four work best; groups of three also work if each student handles one extra strip.
- Open by writing the two paragraph ideas on the board: what the pump station does, and how the crew keeps it running. Tell students that every strip either supports one of those two ideas or supports neither.
- Give each group an envelope and two work spaces, one for each paragraph. Ask groups to spread all twelve strips face up before moving any of them.
- Round one, six minutes: groups find the two topic sentences first and place one at the top of each work space. Circulate and ask groups how they knew a strip was a topic sentence rather than a detail.
- Round two, ten minutes: groups place the remaining strips. Any strip that supports neither idea goes in a third pile called Leftovers. Stop the round when every group has exactly two strips in Leftovers.
- Round three, eight minutes: groups read each finished paragraph aloud in order, listening for a sentence that sounds out of place, and move strips if the reading tells them to.
- Each student then completes the recording page alone, answering items 1 through 10.
- End the activity when every student has written both headings and both closing sentences. Debrief with two questions. First, ask which strip caused the longest argument in the group and how the group settled it. Second, ask what a reader would lose if the two paragraphs were mixed together into one long block.
Student Handout
The Plumridge booster pump station is made up for this activity, and so is the Highfield neighborhood it serves. Your group has twelve sentence strips. Build two paragraphs. Two strips belong in neither one.
Strip A. The Plumridge booster pump station moves drinking water uphill to the Highfield neighborhood.
Strip B. Water leaves the town storage tank and flows into the station through a wide pipe.
Strip C. Inside the station, three electric pumps push that water up the hill.
Strip D. Only one pump runs at a time, and the other two wait in case it stops.
Strip E. Without the pumps, water could not climb the last steep block to Highfield.
Strip F. Two crew members keep the station running all year.
Strip G. Every Tuesday a crew member walks through the station and listens to each pump.
Strip H. The crew changes the oil in all three pumps twice a year.
Strip I. When a gauge reads low, the crew calls the water plant before touching anything.
Strip J. The crew writes every check in a log book that the state may ask to see.
Strip K. The Plumridge farmers market opens on Saturday mornings in the town square.
Strip L. Highfield Elementary won the town spelling contest in March.
Answer items 1 through 10 on your recording page.
- Which strip is the topic sentence for the paragraph about what the station does?
- Which four strips are the details for the paragraph about what the station does?
- Which strip is the topic sentence for the paragraph about the crew?
- Which four strips are the details for the paragraph about the crew?
- Which two strips belong in neither paragraph?
- Explain why strip K belongs in neither paragraph. Use the words on the strip in your answer.
- Write a heading of five words or fewer for the first paragraph.
- Write a heading of five words or fewer for the second paragraph.
- Write a closing sentence for the first paragraph.
- Write a closing sentence for the second paragraph.

Answer Key
- Answer: Strip A. It names the station and states the one job the whole paragraph explains.
- Answer: Strips B, C, D, and E. Each one tells more about how water moves through the station and up the hill.
- Answer: Strip F. It names the crew and states what the paragraph will explain about them.
- Answer: Strips G, H, I, and J. Each one names something the crew does to keep the station working.
- Answer: Strips K and L. Neither one says anything about the pump station or its crew.
- Answer: Strip K is about the farmers market in the town square, so it tells nothing about how water reaches Highfield or about what the crew does. Accept any answer that quotes or restates the market wording and states that the strip supports neither idea.
- Answer: Accept any accurate heading of five words or fewer, such as "What the pump station does" or "Moving water uphill to Highfield."
- Answer: Accept any accurate heading of five words or fewer, such as "How the crew keeps it running" or "The Plumridge crew's weekly checks."
- Answer: Accept any closing sentence that sums up the first paragraph without adding a new fact, such as "The three pumps are the reason Highfield has water at all."
- Answer: Accept any closing sentence that sums up the second paragraph without adding a new fact, such as "Steady checks are what keep the pumps ready every day."
Differentiation
Support
Give these groups an envelope with strips A and F already marked with a star so the topic sentences are settled before sorting starts. Allow items 7 through 10 to be dictated to a partner who writes them down, and accept a heading of two or three words.
Extension
Ask these students to write two more strips that would fit the first paragraph and one more that would fit neither, then hand all three to another group to sort. The stray strip must be a true sentence about Plumridge, not nonsense, so that the sorting still takes thought.
ELL supports
Pre-teach pump, tank, gauge, and crew with a labeled sketch of the station on the board, and note that check on strip J means an inspection rather than a mark or a payment. Let students sort the strips and explain their grouping orally before writing any item.
Extensions
Have the class combine the two finished paragraphs into a one-page notice for Highfield families explaining why water pressure drops for an hour during a pump repair. Students must keep the two paragraphs separate under their headings and add one new closing line for the whole page.
