Writing with Synonyms Worksheet

A third grader who only ever writes happy, run and big is writing with a very small toolbox. This Writing with Synonyms Worksheet hands them eight better words and asks them to put each one to work inside a real sentence, so synonyms stop being a vocabulary list and start being a choice a writer makes.

The worksheet opens with a word box holding eight synonyms, then gives eight sentences with one plain word underlined in each. Students read the sentence, decide which box word means the same as the underlined word, and write it on the line beside the item. Because the answers do not run in the order of the box, a child cannot pair them by position; every item has to be read. Each word is used exactly once, so students can cross off the box as they go and use the leftovers to check their own work. The complete answer key is on the second page.

What’s Included

• A word box of eight third grade synonyms in alphabetical order
• Eight sentences with one underlined word to replace, each with its own writing line
• Answers scrambled against the box, so the task cannot be solved by position
• A hand drawn illustration of objects pulled straight from the sentences
• A full answer key on the final page, and a printable PDF ready for school or home

Three reasons this resource helps kids learn this skill. First, the synonym arrives inside a sentence rather than beside a definition, so the child meets the word the way a reader actually meets it. Second, matching a plain word to a richer one is the exact move that lifts a paragraph out of flat writing, and it transfers straight into the next story a student drafts. Third, the one word per item design makes the page self checking: a leftover box word is a signal to go back and reread, which builds the habit of revising instead of guessing.

Ideas for teachers and parents. Before the page, play a quick round of word tennis: say a plain word and let students volley back every synonym they know. After the page, have each student pick two items and rewrite the whole sentence using the new word, then read both versions aloud and decide which sounds better and why. Keep a class synonym wall and add every word from the box to it. For an extra challenge, ask students to find a ninth plain word in their own writing and replace it. At home, this 3rd grade synonyms worksheet pairs well with a thesaurus and ten minutes at the kitchen table. Using the writing with synonyms worksheet alongside an antonyms page gives students both halves of the same vocabulary skill.
