First Grade Synonyms and Antonyms Worksheets

Beginners can use this worksheet where they’re asked to choose a synonym or antonym from a list of words.

Can you think of other synonym examples for each set of words?

• Big/little
• Glad/mad
• Same/alike
• Good/bad
• Hot/cold
• Easy/hard

Think of an antonym for the underlined word in each sentence. For an extra challenge, see how many antonyms you can come up with for each sentence.

1. It is time to begin our lesson.
2. My food is very hot.
3. Would you please close the door.
4. Do not start running yet.
5. That is a good dog.

This worksheet features two sections, one for synonyms and one for antonyms.

• Use each section of the worksheet to teach a group lesson by completing them together and explaining the answers as you go.
• Take the worksheet a step further and ask kids to write an antonym for each word in the synonym section and a synonym for each word in the antonym section.

• Use the worksheet as a test.

Kids who fully understand the concepts of synonyms and antonyms can move on to a fill-in-the blanks worksheet. Students will need to find synonyms and antonyms on their own in parts of this worksheet.

Can you think of additional antonyms for each set of words?

• Bucket/pail
• Speak/talk

Practice both synonyms and antonyms with these examples.

Learning about synonyms and antonyms helps first graders easily expand their vocabulary. This important part of 1st grade grammar lessons helps you teach new vocabulary words or explain how to find the opposite of words.
