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 pitched at the expected level for Grades 10–12, for practice after the topic has been taught.

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

Tip for grown-ups: Match the pairs your child is sure of first, then work out the rest from what is left.

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