2. Read each instruction aloud together before your child starts.
3. Let your child try every activity independently first.
4. Mark with the answer key on page 2 and talk through any mistakes.

Tip: five to ten minutes of regular practice works better for Grade 1 learners than one long session. Colour in the monkey when the worksheet is finished as a small reward.
