## X08 · Plan a useful comparison notebook

**Complete source:** Original fiction. A maker wants to compare two materials but has only planned a paper gate on one mat and a cloth gate on a different mat with a different start. Neither has been lifted.

**Own invitation:** Which match could you ask to keep for that question? What result must stay open?

**Make or choose:** Sketch an intended same mat/start/edge arrangement for broad familiar pieces. The purpose is planning; it need not be performed. Any later actions and help receive their own actual record.

**Access choice:** Use two large pictures, one spoken change, or a child-directed helper drawing. No checklist completion is required.

**Teacher notice and limit:** Planning a match is not carrying out a fair comparison. A changed material is the intended difference for this question, rather than an automatic flaw.
