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 pitched at the expected level for Grade 8, 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: Use the letter count after each clue and any crossing letters when a clue gets stuck.
