Students practice rewriting sentence pairs to correctly use plural possessive nouns and apostrophes.

The task in the image involves completing sentences using plural possessive nouns. Plural possessive nouns are used to show ownership or possession by more than one person, place, or thing. The general rule for forming plural possessive nouns is:

1. If the plural noun already ends in -s, add an apostrophe (') after the -s.
- Example: "the children's toys"
2. If the plural noun does not end in -s, add both an apostrophe and an -s.
- Example: "the men's room"
