How to use it

1. Teach or review the rule first with the word families lesson. It takes about 10 minutes.
2. Read the directions for each part out loud. Early readers can point while you read.
3. Check Part A together before your child goes on, so any confusion gets fixed early.
4. Use the answer key on the last page.

Prints on US Letter paper (8.5 × 11 in). No sign-up needed.

Tips for doing it together

• Keep it short. One page a day is plenty for most young children, and two short sessions beat one long one.
• Let your child read each sentence out loud before answering. Many mistakes get caught by ear.
• Mark a mistake with a small dot instead of an X, and let your child find and fix it. That's where the learning happens.

What your child is practicing

A word family shares an ending chunk: cat, hat and bat are all -at words. The kindergarten standards ask kids to blend first sounds with chunks and swap sounds to make new words. Part B mixes two families so your child reads every word.
