How to use it

Work through the first program together, one line or arrow at a time. Use a pencil so changes are easy to make. It is one of the easier sheets for Grade 3, good as a warm-up or a first look at the skill.

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

Tip for grown-ups: Let your child move a coin or finger square by square for each arrow.

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