This Grade 4 worksheet on Synonyms is a rich and engaging grammar resource designed to expand the vocabulary of young learners and help them express their ideas more vividly and precisely. Built for Class 4 students, this worksheet teaches children that many words share similar meanings and that choosing the right synonym can make their writing and speaking far more interesting and expressive.
Synonyms are words that have the same or nearly the same meaning — like “happy” and “joyful,” or “big” and “large.” For Grade 4 learners, understanding synonyms is essential because:
They help students avoid repeating the same words in their writing.
They build a richer, more varied vocabulary over time.
They allow students to choose words that fit the mood and tone of a sentence better.
They are a key tool for improving written communication and creative expression.
This worksheet includes five well-structured exercises that take students from basic word recognition to active application of synonyms in sentences:
Exercise 1 – Match the Following
Students match each word on the left to its correct synonym on the right. Pairs include small/tiny, happy/joyful, begin/start, fast/quick, smart/clever, talk/speak, friend/buddy, big/large, help/assist, and quiet/silent.
Exercise 2 – Sort the Words
Students are given a variety of word pairs and must classify them as either Synonyms or Non-Synonyms. This critical thinking task sharpens students’ ability to distinguish between words with similar meanings and words that are opposite, unrelated, or merely sound similar.
Exercise 3 – Fill in the Blanks
Students choose one synonym from a given pair to complete each sentence meaningfully. Context clues in each sentence guide students to select the most fitting word.
Exercise 4 – Multiple Choice Questions
Students select the correct synonym from four answer options to complete each sentence. This familiar exam-style format challenges students to apply their synonym knowledge under slightly more competitive conditions.
Exercise 5 – Sentence Rewriting
Each sentence contains a simple, commonly used word. Students rewrite the sentence by replacing that word with a more expressive synonym. This activity directly trains students to improve their writing quality — one of the most practical vocabulary skills at the Grade 4 level.
