How to use it

Read the rules at the top together and try the first step side by side. Use a pencil so mistakes rub out easily, and check every answer at the end. It is one of the harder sheets for Grade 7, best once the basics of the skill are secure.

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

Tip for grown-ups: Start with the shortest coded words; one- and two-letter words crack the code fastest.

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