Plural noun rules worksheets
Making a noun plural usually means adding -s, but some endings change the rule: fox becomes foxes, bench becomes benches, baby becomes babies. Second graders learn the -s and -es patterns and start noticing which ending a word needs.

Plural noun rules across the grades
1st grade
Plural means more than one, and most nouns show it with a simple -s: one cat, two cats. Words that end in a hissing sound (box, bus, dish) need -es, and first graders pick the right plural with a number word as their clue.
2nd grade
Making a noun plural usually means adding -s, but some endings change the rule: fox becomes foxes, bench becomes benches, baby becomes babies. Second graders learn the -s and -es patterns and start noticing which ending a word needs.
3rd grade
Plural spelling follows patterns: add -s for most nouns, -es after x, ch, sh, and s sounds, -ies for consonant + y words, and -ves for many f words. Third graders work across all the families and catch misspellings like foxs and babys.
