# A handout supply decision · my response


## Complete neutral source

An invented display needs 485 handouts. It has 268 handouts in one pile and 124 in another, counted once. Decide whether the supply meets the need. No real print stock or event is observed.

## Eligibility

After joining counts, differences and interpreting a target comparison have been taught, e.g. Days 51–55 and 59. Formulation is taught before use as a 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 question would settle whether the supply is enough? Write a model with units.

2. Find the exact available count and the amount missing or extra.

3. Make the decision in terms of the source.

4. A made-up note says “about 270+120 is 390, so we know the exact shortfall is 95”. Keep or repair it.

Four own areas initially empty. Reading the native complete source on the same page retains typed words. Reloading, closing or leaving this page can lose them. Use paper if you need a record.
