# A new D case: first thinking

An original plan states whole 29. Its proposed two-part account claims 20 and 8. Decide whether that account fits the stated whole; no verdict or repair is supplied.

[Original source aid](../aids/d-first-source.svg) · [Full source description](../aids/d-first-source-alternative.md).

1. Does this account fit its whole? Check it.

2. Keep the stated whole. Keep or fix the parts. Show why.

3. Give another two-part plan for the stated whole.

4. Show three parts for the same whole. Check them.

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.

Use after Day 48 as appropriate. [Empty own response](../assessment/d-first-own.md) and [separate key](../assessment/d-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.
