Why Prefixes and Suffixes Matter in Class 7?  

This worksheet helps learners:

What’s Inside This Worksheet?  

This worksheet includes five engaging activities:

Learners choose the correct prefixed or suffixed word based on meaning. For example: “What is the correct word for ‘not complete’?” → *incomplete*.

🔍 Exercise 3 – Sorting Prefix and Suffix Words  
From a mixed word bank, learners find and categorize valid prefix- and suffix-based words like *rewrite*, *teacher*, *joyful*, *homeless*.

📝 Exercise 4 – Rewrite the Sentence  
Students correct errors in prefix/suffix use in sentences like “She was unhonest” → “She was dishonest”.

✍️ Exercise 5 – Sentence Creation
