Educational worksheet teaching the rule for using apostrophes in possessive plurals, including examples and practice exercises.

Let me work through this step by step.

The worksheet is about possessive plurals and apostrophes. I need to rewrite each sentence with the correct apostrophe placement.

Rule 1: When the plural form ends in s, put the apostrophe AFTER the s (s')
Rule 2: For irregular plurals that don't end in s, add 's after the plural form

Let me go through each sentence:

1. "The dogs tails were wagging happily."
- Dogs = regular plural ending in s
- So: dogs' tails

2. "After the rainstorm, the womens clothes were sodden."
- Women = irregular plural (doesn't end in s)
- So: women's clothes

3. "The childrens entertainer was amazing."
- Children = irregular plural (doesn't end in s)
- So: children's entertainer

4. "The rabbits noses were twitching."
- Rabbits = regular plural ending in s
- So: rabbits' noses

5. "The aliens bodies were bright green."
- Aliens = regular plural ending in s
- So: aliens' bodies

6. "The pirates beards were long and black."
- Pirates = regular plural ending in s
- So: pirates' beards

7. "The firemens helmets kept them safe."
- Firemen = irregular plural (doesn't end in s)
- So: firemen's helmets

8. "The teams captains shook hands at the end of the match."
- Teams = regular plural ending in s
- So: teams' captains

9. "The mens changing room was untidy."
- Men = irregular plural (doesn't end in s)
- So: men's changing room

10. "The grandchildrens party was a great success."
- Grandchildren = irregular plural (doesn't end in s)
- So: grandchildren's party

Final Answer:
1. The dogs' tails were wagging happily.
2. After the rainstorm, the women's clothes were sodden.
3. The children's entertainer was amazing.
4. The rabbits' noses were twitching.
