About these printables
Second graders match ten antonym pairs (full and empty, push and pull, early and late) and ten synonym pairs (big and large, yell and shout, rock and stone).
The color sort page mixes both: yellow for word pairs that mean the same (grin and smile), blue for opposites (save and spend). Third graders fill a chart with a synonym and an antonym for eight words, such as noisy, loud and quiet. Answer keys on page 2.

Tips for parents and teachers
- Use body actions for opposites: stand up for up, crouch for down, stretch for big.
- When a child repeats the same word in writing (very good, very good), suggest a synonym.
- On the color sort, read each pair aloud and ask: same or opposite?
Did you know?
- A thesaurus is a book of synonyms; the word comes from the Greek for treasure.
- Some words are their own opposites, like dust (to add dust or to remove it).
Fun ways to use your printables
- Play opposites ping-pong: say a word, the other player answers with its opposite.

Frequently asked questions
What is the difference between a synonym and an antonym?
A synonym means the same or almost the same (big and large); an antonym means the opposite (big and small). A simple way to remember: Same starts with S like synonym, and Anti means against.
When are opposites taught?
Opposites are often taught in kindergarten and first grade with everyday words like up and down; the words synonym and antonym usually appear in second grade, with harder pairs in third grade.
How can we practice synonyms at home?
Play a quick game in the car: one person says a word and the other has to say another word that means the same. For antonyms, say a word and answer with its opposite as fast as you can.
