Irregular Plural Nouns Worksheet
- 2nd grade
- CCSS L.2.1b
A free, printable irregular plural nouns worksheet for 2nd grade. Your child matches mouse to mice and foot to feet, picks the right plural, and fixes mistakes. Answer key included.
What's inside
- Page 1: write the plural for 8 nouns, then circle the right plural in 5 sentences.
- Page 2: fix 3 sentences, then write a sentence with an irregular plural.
- Page 3: answer key.
How to use it
- Teach or review the rule first with the irregular plural nouns 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
Irregular plurals don't add -s or -es: mouse becomes mice, foot becomes feet and child becomes children. The 2nd grade standard names feet, children, teeth, mice and fish. This worksheet uses those five plus a few more that show up in kids' books.
