catsbookstrees Singular nouns name one item like dog and apple. Plural nouns often end in s and name more than one, like cats, books, and trees.
Part B: Fill in the Blank
Write the missing word or number on each line.
1. I have one book on my desk.
Book is the singular form because it names only one item, matching the word one in the sentence.
2. Three dogs are playing outside.
Three is more than one, so we need the plural form dogs by simply adding s to dog.
3. My sister picked one red apple.
Apple is singular because the sentence says one, so no plural ending is needed.
4. The tall trees gave us shade.
Tall trees working together to give shade suggests more than one, so the plural trees fits best.
5. A little cat ran across the yard.
The word a tells us only one animal ran, so the singular cat is correct here.
Part C: True or False?
Read each statement. Circle True or False.
1. The word 'cats' is plural.
True False
Cats ends in s and names more than one cat, so it is a plural noun.
2. The word 'book' is plural.
True False
Book names only one item, so it is singular, not plural.
3. Plural nouns name more than one.
True False
Plural means more than one, so this statement is correct by definition.
4. The word 'girl' names many girls.
True False
Girl does not end in s and names only one person, so it is singular.
