- Which word correctly completes the sentence? Maya brushes one tooth. She brushes many ___.
Answer: teeth
This tests CCSS.L.2.1.b (forming and using frequently occurring irregular plural nouns like feet, children, teeth, mice, fish). Most plural nouns are formed by adding -s (cats, dogs) or -es (boxes, dishes), but irregular plurals don't follow this rule. Common irregular plurals 2nd graders should know: foot→feet (change vowel), tooth→teeth (change vowel), child→children (add -ren), mouse→mice (change vowel), man→men and woman→women (change vowel), fish→fish and sheep→sheep and deer→deer (no change), goose→geese (change vowel), leaf→leaves, knife→knives, shelf→shelves, and wolf→wolves (change -f to -ves). Students must memorize these because they don't follow the regular pattern. Choice D is correct because "teeth" is the proper plural form of "tooth." This is a frequently occurring irregular plural that follows the vowel change pattern. Choice B shows adding -s incorrectly. Second graders often try to add -s to all plurals even irregular ones, use singular form as plural, mix up vowel changes, forget to change -f to -v. To help students: Create irregular plural chart organized by pattern: Vowel Change (foot-feet, tooth-teeth, man-men, woman-women, goose-geese, mouse-mice), Add -ren (child-children, ox-oxen), No Change (fish-fish, sheep-sheep, deer-deer), F→V (leaf-leaves, knife-knives, wolf-wolves, shelf-shelves, loaf-loaves). Practice with flashcards: singular on one side, plural on other. Use memorable sentences: "One tooth, two teeth, all my teeth!" "One child, two children, many children." Read aloud books that use irregular plurals naturally, point them out. Make it physical: Have students show one foot, then both feet. Count teeth in mirror. Sorting activity: regular plural cards vs irregular plural cards. Common error correction: When student says "foots" or "childs," gently correct "Remember, it's feet, not foots. Foot-feet is an irregular plural." Watch for: students adding -s to irregular nouns (foots, childs, mouses, sheeps), students using singular as plural ("two tooth"), students confused by no-change plurals (fish-fish, sheep-sheep, deer-deer).
