Give play a purpose.
10 minutes, one good conversation
- Notice · 2 min. Ask what the pieces represent. Make a prediction before pressing anything.
- Explore · 5 min. Work alone or in pairs. Take turns explaining a choice. Hints and retries are part of learning. Try building the model before opening the worked answer.
- Explain · 3 min. Show a second way to reach the same answer. What stayed the same? What changed?
What students practise
Fraction Foundry: equal parts, equivalent fractions and visual comparisons. Supplemental practice for parts of Common Core 3.NF.A and 4.NF.A; it does not cover either standard in full.
Signal Loom: spatial logic and reasoning enrichment. Ask students to describe a path and justify each turn.
