Plural Rules Worksheet (Free PDF)

Three rules that cover almost every English plural, one practice page each.

What’s inside

• An instructions page.
• Rule 1 — Just Add -s (cat + s →, dog + s →, book + s →).
• Rule 2 — Add -es after s, x, z, ch, sh (box + es →, bus + es →, buzz + es →) and Rule 3 — Y to IES.

How to use it

1. Read the rule and the base word.
2. Add the ending and write the plural.
3. Say it aloud: -es adds a whole extra beat (box-es).
4. Mix all three rules in a quick oral quiz at the end.

Watch out for

• -es after s, x, z, ch and sh adds a whole extra beat (box-es); -s alone doesn't (cats). Say both aloud to hear it.
• Y to -ies only happens after a consonant (baby → babies); after a vowel, just add -s (boy → boys).
• Irregular plurals (children, mice, feet) follow none of the three rules — keep a separate list.
