The new model has four verified ten-strips and six loose marks. Each strip has ten countable cells. Replacement singles are available. The final whole or opened-ten answer is not labelled.
Replace one ten-strip with singles. Show the new parts.
How do you know the amount stayed the same?
Keep your first idea before help. You can point, select, speak, sign, use AAC or direct an adult’s marks/moves. Tell the grown-up if the amount or layout needs changing.
Grown-up help
Use after Day 45 as appropriate. [Empty own response](../assessment/b-first-own.md) and [separate key](../assessment/b-first-key.md) have different roles. [Fresh preparation and eligibility](SELECT.md). Source givens, adult movements, mathematical hints and actual smaller ranges are named. This is a formative case, not secure or a whole-year grade.
Source review is complete for this two-week edition. Local suitability and classroom use still need review. Earlier candidate or pending-review words are retained in the original files; full-year coverage, translations and audio are not claimed.
Labels and search exclusions are distribution guidance; they do not authenticate or restrict access.
