Of course! Let's solve each problem step by step and write the correct number sentence for each.
---
Problem 1:
> 16 boys played in the mud.
> Then 3 more come.
> How many boys played in the mud?
- We start with 16 boys.
- Then 3 more join them → we
add.
- So, the total number of boys is:
16 + 3 = 19
✔ Number Sentence:
16 + 3 = 19 boys
---
Problem 2:
> There are 10 green apples and 4 red apples.
> How many apples are there in all?
- We have two groups: green apples (10) and red apples (4).
- To find the total, we
add them together.
10 + 4 = 14
✔ Number Sentence:
10 + 4 = 14 apples
---
Problem 3:
> There are 26 red ants.
> Then 5 of them crawl away.
> How many ants are left?
- We start with 26 ants.
- 5 leave → we
subtract.
26 - 5 = 21
✔ Number Sentence:
26 - 5 = 21 ants
---
Problem 4:
> 30 birds fly in the tree.
> Then 7 more birds fly in the tree.
> How many birds are in the tree?
- We start with 30 birds.
- 7 more join → we
add.
30 + 7 = 37
✔ Number Sentence:
30 + 7 = 37 birds
---
✔ Final Answers:
1.
16 + 3 = 19 boys
2.
10 + 4 = 14 apples
3.
26 - 5 = 21 ants
4.
30 + 7 = 37 birds
