When students verbalise their thinking, they clarify ideas. When they hear peers' thinking, they expand their own. Talk is how understanding deepens.
Why Talk in Maths?
Talking Stems
Provide sentence starters so students know how to talk about maths:
- "I think the answer is ___ because ___"
- "I agree with ___ because ___"
- "I disagree because ___"
- "Another way to solve this is ___"
- "This is similar to ___ because ___"
Maypole / Carousel
Students stand in concentric circles facing a partner. Pose a question. Partners discuss for 30 seconds. Outer circle rotates. New partners discuss the same question. Quick, energetic, everyone talks.
Small Group Problem-Solving
Groups of 3-4 solve a problem together. One person records. Everyone contributes. You circulate, listen, ask: "How did you get that? Why does that work? What if...?"
Debate / Defend Your Answer
"Is 12 ÷ 3 the same as 3 × 4? Defend your answer." Pairs or small groups argue. Forces deep thinking about relationships.
Jigsaw
Divide the class into "expert groups," each learning one aspect of a concept. Then regroup so each new group has one expert. Experts teach each other. Everyone learns all parts.
Example: Fractions unit. Group A learns halves. Group B learns thirds. Group C learns quarters. Then regroup so each student teaches their expertise.
