Before and Beyond: Exploring Prefixes and Word Meaning in Class 3

This Grade 3 English grammar worksheet introduces prefixes and how they change word meaning in a simple and engaging way. Students learn that adding a prefix to the beginning of a word can completely change what the word means.
The worksheet focuses on common prefixes such as re-, un-, pre-, post-, over-, under-, mis-, and dis-. Through clear multiple-choice questions, learners practice identifying words that show repetition, time, degree, or incorrect action.
Designed especially for Class 3 students, the activities use familiar words and real-life examples to make abstract grammar concepts easy to understand. Each exercise builds logical thinking and helps children connect meaning with word structure.
By completing this worksheet, students develop stronger vocabulary skills, better reading comprehension, and confidence in understanding how words are formed and used correctly.

Why Prefixes Matter in Grammar?
Prefixes help learners understand meaning quickly by breaking words into parts. For Grade 3 students, this topic is important because:
1. Prefixes change word meanings in clear and predictable ways.
2. Understanding prefixes helps students guess meanings of new words.
3. It improves vocabulary, spelling, and reading confidence.
4. These skills support clearer writing and accurate word usage.
