Let’s go through each sentence one by one and pick the correct plural form.
---
1. There were ten ___ playing on the beach.
Options: *childrens* / *children*
→ “Child” becomes “children” in plural — not “childrens”. That’s irregular!
✔ Correct:
children
---
2. Maggie lost one ___ last year.
Options: *tooth* / *teeth*
→ The sentence says “one”, so we need the singular form.
“Teeth” is plural (like two or more). “Tooth” is singular.
✔ Correct:
tooth
---
3. We saw five ___ in the woods.
Options: *deers* / *deer*
→ “Deer” is special — it stays the same in singular and plural! No “s” needed.
So, “five deer” is correct. Not “deers”.
✔ Correct:
deer
---
4. Cats scare one ___ away.
Options: *mouse* / *mice*
→ Again, “one” means singular. “Mouse” is singular. “Mice” is plural.
✔ Correct:
mouse
---
5. I have two ___.
Options: *feet* / *feets*
→ “Foot” becomes “feet” in plural — never “feets”. That’s another irregular one!
✔ Correct:
feet
---
Final Answer:
children
tooth
deer
mouse
feet
