Code: AC9M6N03. Goal: transfer equivalent-name, order and same-whole reasoning to unseen 5/3 and 7/4 plus a new 24-tile context. Prepare: closed learner check, blank line/strips, separate staff key.
- Launch · 2 min. Remind learners to mark 0, 1 and 2 before deciding an order; response mode is open.
- Model · 5 min. Revisit different numbers:
5/4=15/12,3/2=18/12; put away. Do not show the check's5/3or7/4. - Guided · 6 min. Use
1/4=3/12and1/2=6/12on one fixed 0–1 line. Ask why six gaps on a 12-gap line represent half. Put it away. - Independent check · 6 min. Give unseen Day 20 Items 1–2. Adult can read wording neutrally or provide a tactile line without placing answers.
- Check exit · 4 min. Item 3 asks for a same-whole comparison and a false-rule repair. Preserve first response and route; D20 choices are later practice.
- Note · 2 min. Mark endpoints/equal scale, equivalent names, order and justification separately. If learner had no usable access route, mark not yet observed and arrange a valid later check.
Home/extension: Fresh check stays in class. Afterward, optional D20 routes use different numbers and a learner-selected everyday context.
Later in the day: The ten optional extra cards give short practice or transfer, not a full mathematics timetable. No learner needs a home device, purchase or personal finance disclosure. The exact curriculum descriptions and taught limits are in the crosswalk. Original SubjectNest lessons © NeuroForgeIO Pty Ltd 2026, CC BY 4.0.
