Let's solve each problem step by step and explain the reasoning.
---
Problem 1:
Question: Henry had 3 marbles. Mia gave him 4 more. How many marbles does Henry have now?
- Henry starts with
3 marbles.
- Mia gives him
4 more.
- To find the total, we
add the two amounts:
$ 3 + 4 = 7 $
✔ The correct operation is
3 + 4.
✔️ The red circle around
3 + 4 is correct.

Problem 2:
Question: Jo had 8 cookies. She gave 4 of them to Rory. How many cookies are left with Jo?
- Jo starts with
8 cookies.
- She gives away
4 cookies.
- To find how many are left, we
subtract:
$ 8 - 4 = 4 $
✔ The correct operation is
8 - 4.
✘ The option
4 + 8 is incorrect because that would be adding, not taking away.
✔️ So, the correct answer is
8 - 4.

Problem 3:
Question: Ben has 5 toy ducks and 2 airplanes. How many toys does Ben have in all?
- Ben has
5 toy ducks and
2 airplanes.
- To find the total number of toys, we
add both:
$ 5 + 2 = 7 $
✔ The correct operation is
5 + 2.
✘ The option
5 - 2 is incorrect because we are combining items, not removing.
✔️ So, the correct answer is
5 + 2.

✔ Final Answers:
1.
3 + 4 → Correct (already circled)
2.
8 - 4 → Correct
3.
5 + 2 → Correct
You should
circle:
-
3 + 4 for question 1
-
8 - 4 for question 2
-
5 + 2 for question 3
These represent the correct operations for each word problem.
