This Grade 4 grammar worksheet introduces students to the important concept of prefixes using “over-” and “under-”. Designed to build a strong foundation in word formation, this worksheet helps learners understand how prefixes change the meaning of base words in clear and practical ways.
By working through engaging activities like true or false, word sorting, fill in the blanks, multiple choice questions, and sentence writing, students develop a deeper understanding of how to correctly use “over-” (meaning too much or excessive) and “under-” (meaning too little or insufficient).
Understanding prefixes is essential for vocabulary development and reading comprehension. For Grade 4 learners, this topic is important because:
1. Prefixes change the meaning of base words in predictable ways.
2. “Over-” helps express excess, while “under-” shows lack or insufficiency.
3. It improves spelling, word recognition, and sentence construction.
4. It builds confidence in both written and spoken communication.
This worksheet includes five grammar-focused exercises that strengthen understanding of prefixes:
Exercise 1 – True or False
Students read statements about prefixed words and identify whether the meanings are correct or incorrect. This sharpens their understanding of word meanings.
Exercise 2 – Sort the Words
Students add the correct prefix (over- or under-) to base words and sort them into the correct columns. This helps reinforce usage through categorization.
Exercise 3 – Fill in the Blanks
Students complete sentences by choosing the correct prefix based on context (too much or too little). This builds real-life application skills.
Exercise 4 – Multiple Choice Questions
Students select the correct prefixed word based on given meanings. This enhances accuracy and grammar clarity.
Exercise 5 – Sentence Writing
Students create meaningful sentences using given prefixed words. This encourages creativity and practical usage of grammar concepts.
