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 Grade 12, for practice after the skill has been taught.

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

Tip for grown-ups: Find the oldest and newest events first, then fill in the middle.

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