Useful outcome
Keep your first idea and choose one next maths invitation. Use existing safe pieces, original marks or the empty own organiser · Complete terms. Full description. The child may keep the product private.
Prepare and check entry
Prepare the ordinary whole 18 and separate counted/waiting space, two or three parts as relevant, large numeral cards and optional verified ten-strips. Audit a ten before using it. Ask for one-to-one coverage and value of a full unit. Teach missing entry knowledge on a new small collection before today's larger example. Smaller actual quantities remain useful and are named.
Run the 25-minute component
- Start, 3 minutes: offer the useful outcome. Ask what amount is being organised and how we can include each object once.
- Model, 5 minutes: 10 + 8 = 18. Another account is 6 + 12 = 18. These describe one original collection. Verify each part and include each object once. Choose a new ordinary case or a staff fresh case suited to the components taught. Keep the first thinking before feedback. Check objects, parts and whole. Make a useful revision when needed, or keep a supported account. Pick one next invitation.
- Try together, 7 minutes: the child selects boundaries/members; an adult may move marks at their direction. Ask “What is in each part? What stayed the same?” Check by the actual members, not only matching printed numerals.
- Choose, 7 minutes: take one of Two-job kit, Open-ten plan, Three-job notes. Different purposes/quantities give new work; they are not fixed sensory learner labels.
- Show and check, 3 minutes: ask for today's relevant part values, whole and one reason. Keep first thinking/support, then a revision if needed. A model already supplied is not independently invented.
- Next invitation: Choose the next teaching by the missing component: coverage, unit value, replacement, changed parts, or justified keep/repair. Use a different small example and then a new case, not the same memorised answer.
Likely confusion and response
A copied answer or prompted exchange is named as support. A smaller successful sample is useful without standing for an unperformed larger task. Choose the next teaching by the missing component: coverage, unit value, replacement, changed parts, or justified keep/repair. Use a different small example and then a new case, not the same memorised answer.
What to notice
Look for correct whole/part membership, matching quantities, the day's particular exchange/transfer/check and a supported reason. A correct whole alone does not prove every component. A child can choose a valid partition different from the model. Record actual quantity, access support and mathematical prompts; do not grade voice, handwriting, speed or motor independence.
