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 easier sheets for Grade 9, 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: 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.
