How to use it

Cut the pieces out first; with younger children, that is a grown-up job. Sort the pieces into groups before gluing them down. It is one of the easier sheets for Kindergarten to Grade 1, good as a warm-up or a first look at the skill. Its 2 pages split well across two sittings.

An answer key comes with it as a separate page that grown-ups download after signing in.

Tip for grown-ups: Ask why each card belongs in its group before it is glued down.

Done on paper? A grown-up can record it on the child's page in PlayOwl; downloading alone doesn't count as finished.
