How to use it

Try the first question together so the format is clear. Then let your child work through the rest, showing their thinking on the page. It is one of the harder sheets for Grades 2–3, best once the basics of the skill are secure.

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

Tip for grown-ups: Check the first three problems together before your child carries on alone; most mix-ups show early.

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