Tips for using it

• Do one grammar sheet at a time and read the instructions aloud together; the rule usually fits in one sentence.
• Ask children to say each sentence out loud before they write: most grammar mistakes sound wrong when spoken.
• Use the answer key to let older kids check their own work with a colored pencil.
• Mix one picture sheet with one writing sheet per week so grammar does not feel like a test.
