Day 42: Ways to make tenYear 1 Maths · T1 W9–10 · Teacher · Teacher / Day 42

Useful outcome

Make your own ten-parts card. 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 10 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

1. Start, 3 minutes: offer the useful outcome. Ask what amount is being organised and how we can include each object once.
2. Model, 5 minutes: 6 + 4 = 10. Another account is 8 + 2 = 10. These describe one original collection. Verify each part and include each object once. Audit ten objects. Each ten-frame cell is one place, not an object. Try two different splits of those ten. Show zero in one part. Explain where all ten objects are.
3. 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.
4. Choose, 7 minutes: take one of Ten drawing marks, Ten game tokens, Ten blank labels. Different purposes/quantities give new work; they are not fixed sensory learner labels.
5. 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.
6. Next invitation: If zero is treated as missing work, place all ten objects in one region and point to the empty region. If only one split is copied, move one object and recount both parts.

Likely confusion and response

An empty part has zero objects; the frame still has ten places, even when some places are empty. If zero is treated as missing work, place all ten objects in one region and point to the empty region. If only one split is copied, move one object and recount both parts.

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.
