What’s Inside This Worksheet? 

This colorful, rule-based worksheet includes five structured noun exercises: 

✍️ Exercise 1 – Add -s to Make Plurals 
Students change regular singular nouns (e.g., *cat*, *book*) to their plural forms by simply adding **-s**.

📦 Exercise 2 – Add -es for Special Endings 
Learners change words ending in -ch, -sh, -x, -s, or -o to plurals using **-es** (e.g., *box → boxes*).

✏️ Exercise 3 – Change 'y' to 'ies' 
Nouns ending with consonant + **y** (e.g., *lady*, *story*) are transformed to their correct plural forms by changing **y to ies**.

🍃 Exercise 4 – Change 'f' or 'fe' to 'ves' 
This activity teaches how to pluralize nouns like *leaf → leaves* or *knife → knives* by replacing **f/fe with ves**.
