The kind of sentences you'll get

Circle the letter of the word that means almost the same.

  1. The pyramids were built thousands of years ago, so those ancient monuments are truly . old · shiny · new

    Answer: old

  2. Another word for brave is . cowardly · hungry · courageous
  3. Our class will observe the eclipse on Monday, and we will the sky through special glasses. mop · watch · avoid

Every print pulls a fresh set of sentences at this level, so a make-up test or a second sibling never gets the same sheet.

What's on each sheet

Every version prints on US Letter or A4, with its answer key on the last page.

How to teach this

Connect straight to revision. Have students write a sentence with a plain word (nice, big, said), then upgrade it using a synonym and discuss what changed. Word-choice muscles built here show up in every writing assignment after; the worksheet is the gym.

Watch for: Synonyms mean almost the same, not exactly the same. Big and gigantic are both large, but gigantic is bigger. A word about the same topic isn't a synonym: orange isn't a synonym for pumpkin just because pumpkins are orange.

Common questions about synonyms

Do synonyms mean exactly the same thing?
Almost never, and that's the interesting part. Big, huge, and colossal climb a ladder of size; said, whispered, and announced differ in volume and drama. Fourth graders who notice those shades start making real word choices in their writing.
How does this help with writing?
It's the antidote to tired words. When every character is nice and everything is big, a stocked synonym bank offers kind, generous, enormous, towering. Worksheet practice makes the alternatives available at the exact moment a young writer reaches for a word.
