A plural word is more than one of a person, place, or thing. When making plurals, remember:
--change y to i and add es;

--words that end in sh, ch, x, or z add es;

--change f to v and add es.

Write each sentence with the plural form of each underlined word.

1. The squirrel are hiding in the ditch.

2. You will see seal at many beach.

3. Put the firefly in the jar.

4. How many berry did you pick from the bush?

5. Put the letter in the mailbox.
