What's inside
- Page 1: add three endings to 5 base words, then write the base word for 6 longer words.
- Page 2: sort 6 -ed words by sound, then write two sentences.
- Page 3: answer key.
How to use it
- Teach or review the rule first with the word endings: -s, -ed, -ing lesson. It takes about 10 minutes.
- Read the directions for each part out loud. Early readers can point while you read.
- Check Part A together before your child goes on, so any confusion gets fixed early.
- 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
Endings like -s, -ed and -ing change how a word is used. The 1st grade standard asks kids to read words with endings and find the base word. Remind your child to cover the ending, read the base word, then add the ending back.
