Question 1

1. tooths
2. teeth (correct answer)
3. teeths

Explanation: This tests special plural words. 'Teeth' is the special plural of 'tooth'. The word changes for more than one.

Question 2

1. children (correct answer)
2. childes
3. childs
4. child

Explanation: 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 B is correct because "children" is the proper plural form of "child." This is a frequently occurring irregular plural that follows the add -ren pattern. Choice A 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).

Question 3

1. leaf
2. leafs
3. leaves (correct answer)
4. leavs

Explanation: This tests CCSS.L.2.1.b (forming and using frequently occurring irregular plural nouns like feet, children, teeth, mice, fish).

Question 4

1. goose
2. gooseses
3. geese (correct answer)
4. gooses

Explanation: The plural of goose is a special word that does not just add s or es. Goose is the word for only one, not for three. Gooseses and gooses are not real words, even though they look like they should work. Geese is correct because it is the special plural form of goose.

Question 5

1. feets
2. foots

Students must memorize these because they don't follow the regular pattern. Choice C is correct because "feet" is the proper plural form of "foot." This is a frequently occurring irregular plural that follows the vowel change pattern. Choice A shows adding -s incorrectly after vowel change.
