Plural and Possessive Nouns — Answer Key
Part A: Fix the Sentence
Each sentence has an error. Rewrite it correctly on the line.
1. Fix the sentence:
The leafs fell from the tall oak tree.
Corrected: The leaves fell from the tall oak tree.
Leaf becomes leaves because f changes to ves in the plural.
2. Fix the sentence:
Mom used two knifes to cut the bread.
Corrected: Mom used two knives to cut the bread.
Knife ends in fe, so the plural becomes knives in Grade 3 spelling.
3. Fix the sentence:
The wolfs howled loudly at the bright moon.
Corrected: The wolves howled loudly at the bright moon.
Wolf changes f to ves, so more than one wolf is wolves.
Part B: Fill in the Blank
Write the missing word or number on each line.
1. A cat has nine lives according to the old saying.
Life becomes lives because fe changes to ves in the plural form.
2. The baker pulled three warm loaves out of the oven.
Loaf ends in f, so the plural noun is loaves in Grade 3.
3. We raked a huge pile of red and gold leaves today.
Leaf becomes leaves by swapping f for ves, a Grade 3 plural pattern.
4. The campers packed sharp knives for cutting rope.
Knife ends in fe and changes to ves, making the plural knives.

Read each statement. Circle True or False.

Leaf ends in f and changes to ves, so leaves is the correct plural.
