A pretend badge cupboard · paper response

Complete neutral source

A fictional badge cupboard has 364 badges. Another parcel supplies 278 badges of the same kind. Count each badge once. The task is to find the new total; no actual stock or delivery is claimed.

Eligibility

After joining like counts and regrouping have actually been taught with ordinary sources, e.g. Days 51–52. If not, teach first or treat as supported exploration, not an unseen first check.

Access and help

Read or sign the exact source and prompts neutrally, enlarge them, or scribe the learner’s chosen words. A figure, operation, regrouping, equation role or check supplied by an adult is mathematical help and is recorded as such. Show, draw, type, sign or use usual communication. One component can be enough; pause/pass/finish are choices. Four own spaces are genuinely empty. Models, criteria and next lessons stay on separate staff pages.

First later limit

First/later are opportunity labels, not fixed order, matches, calibrated difficulty or learning gain. If source/answer exposed, record that rather than claim unseen.

Prompts

1. What does each count represent? Write a number sentence for the new total.

2. Find the total using a way you can explain or show.

3. Show why any regrouping in your way keeps the amount unchanged. If your way uses no written regrouping, describe crossing a ten or hundred.

4. Give a connected check and state what your total counts.
