Explanation:
We need to find the plural form of each noun in parentheses and write it in the blank. The worksheet reminds us that some nouns have irregular plurals — no rules, just memorization.
Let’s go one by one:
1.
goose → plural is
geese
(Not “gooses” — irregular)
2.
person → plural is
people
(Sometimes “persons” is used in formal/legal contexts, but standard plural is *people*.)
3.
deer → plural is
deer
(Same singular and plural — like sheep/moose)
4.
sheep → plural is
sheep
(Same as singular)
5.
man → plural is
men
(Irregular: man → men)
6.
cactus → plural is
cacti
(Latin origin; also *cactuses* is acceptable, but *cacti* is more traditional and likely expected here.)
7.
tooth → plural is
teeth
(Like *foot → feet*, *tooth → teeth*)
8.
die (as in dice for games) → plural is
dice
Note: “die” is singular; “dice” is plural. Though modern usage sometimes uses *dice* for both, the worksheet expects *dice* as plural.
9.
salmon → plural is
salmon
(Same singular and plural — like deer, sheep)
10.
elk → plural is
elk
(Also same singular and plural — though *elks* is sometimes used informally, standard English treats *elk* as unchanged.)
Let’s double-check:
1. geese
✔
2. people
✔
3. deer
✔
4. sheep
✔
5. men
✔
6. cacti
✔ (most likely expected)
7. teeth
✔
8. dice
✔
9. salmon
✔
10. elk
✔
All match standard irregular plural forms taught at this level.
Final Answer:
1. geese
2. people
3. deer
4. sheep
5. men
6. cacti
7. teeth
8. dice
9. salmon
10. elk
