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

Which word correctly completes the sentence? One leaf fell; many   fell.

  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). 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 "leaves" is the proper plural form of "leaf." This is a frequently occurring irregular plural that follows the -f to -ves pattern. Choice A shows adding -s incorrectly; second graders often try to add -s to all plurals even irregular ones. To help students: Make it physical: Have students show one foot, then both feet. Count teeth in mirror. Sorting activity: regular plural cards vs irregular plural cards.
