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:
Three deers wandered into our backyard this morning.
Corrected: Three deer wandered into our backyard this morning.
Deer is an unchanged plural noun, so we never add s in Grade 3.
2. Fix the sentence:
The farmer counted twelve sheeps in the green field.
Corrected: The farmer counted twelve sheep in the green field.
Sheep does not change form when plural, so sheeps is incorrect.
3. Fix the sentence:
We watched colorful fishes swim around the coral reef.
Corrected: We watched colorful fish swim around the coral reef.
Fish stays the same for one or many in standard Grade 3 writing.
Part B: Fill in the Blank
Write the missing word or number on each line.
1. A herd of ten deer ran quickly across the open meadow.
Deer is an unchanged plural noun, so no s is added even for many.
2. The shepherd guided his sheep safely back to the barn.
Sheep keeps the same spelling whether singular or plural in Grade 3.
3. Many tiny fish darted around the clear pond water.
Fish is commonly unchanged as a plural noun in Grade 3 writing.
4. Our school library has three series of mystery books.
Series is an unchanged plural, so it stays series for one or many.
Part C: True or False?
Read each statement. Circle True or False.
1. In Grade 3, the plural of deer is deers.
True False
Deer stays the same for singular and plural, so deers is wrong.

True False
Sheep is an unchanged plural noun, meaning the form never changes.
3. The word series changes to serieses when plural in Grade 3.
True False
