Day 5 — Equivalent forms and sensible precisionYear 7 Maths · T1 W1–2 · Day 5 lesson

Codes: AC9M7N04, AC9M7N05. Goal: sample Week 1 knowledge and choose next teaching. Prepare: Check A, benchmark strip, quiet station.

1. Purpose · 2 min. Say: “Show how you know, then check if your answer makes sense on a 0–1 line.”
2. Warm-up · 5 min. Together rename 1/2, 0.5, 50% and round 4.238 to a tenth (4.2). This is rehearsal, not scored evidence.
3. Equivalence task · 6 min. Everyone writes 2/5 = 0.4 = 40% and places it relative to 0.25 and 0.5. Observe planned focus learners privately while others check a partner's reason.
4. Precision task · 7 min. Round 12.684 to tenths (12.7), then choose larger of 0.65 and 3/4 (0.75). Require a numeric reason; a correct guess alone leaves the strategy unobserved.
5. Feedback · 3 min. Name the precise work: “You made 2/5 into 4/10. Now let's connect four tenths to forty percent.” Let the learner repair one step, recording the prompt.
6. Close · 2 min. Child names one helpful representation. Teacher selects the next model from the key, marking individual evidence independent / prompted / not yet observed.

Access: verbal or tactile line, AAC/written equivalence, separate quiet interview later if the partner's answer concealed independence.
