Snowball Write-Around

Groups write a paragraph collaboratively, passing the paper around. Each student adds one sentence, building on the previous. The paragraph "snowballs" as it accumulates contributions.

Procedure

1. Groups of 4. One blank page per group, one pen.
2. Teacher sets a prompt: Describe the perfect Saturday / Argue for or against uniforms / Describe an invention the world needs.
3. Student 1 writes the first sentence — the topic sentence.
4. Passes to Student 2, who reads the whole paragraph so far, then adds one sentence.
5. Continues around the group. Each student adds one sentence, always after reading from the start.
6. After 8–12 sentences, the group reads the paragraph aloud. Discuss: what worked? What was jarring?
7. Second pass: revise together, smoothing transitions and fixing errors.

Why It Works

• Forced cohesion: each student must fit with what came before — cohesion devices, tense consistency, logical flow.
• Everyone contributes: equal responsibility for the final paragraph.
• Reading-writing-rereading: the cycle of passing forces constant re-reading, which tightens comprehension.
• Collaborative ownership: the paragraph is nobody's and everybody's.

Variations

• Genre snowball: each new sentence must match a set genre (horror, news report, academic).
• Grammar-locked: every sentence must use a specified structure (passive / third conditional / reported speech).
• Two-group swap: group A writes half; passes to group B who finishes. Reveals different styles.
• Silent snowball: no speaking allowed during the passing. Only the paragraph speaks.

Tips

• One sentence only per turn. Enforce strictly — multi-sentence contributions destroy the balance.
• Re-read the whole paragraph every pass — the re-reading is the engine.
• Keep the prompt open enough to allow multiple directions; too narrow kills creativity.
• Great revision activity: after the final draft, students compare their individual writing habits to the collaborative paragraph — often surprising in what emerged.
