How to use it

Read the first across clue together so the format is clear. Use a pencil so mistakes rub out easily, and check every answer at the end. It is one of the harder sheets for Grade 10, best once the basics of the topic are secure.

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

Tip for grown-ups: Use the letter count after each clue and any crossing letters when a clue gets stuck.

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