To solve these problems, we need to add a single-digit number to a two-digit number. We can use the bar model to help visualize the addition.
Let's solve each problem step by step:
1.
16 + 8
- Start with 16.
- Add 8 to it: 16 + 8 = 24.
2.
23 + 5
- Start with 23.
- Add 5 to it: 23 + 5 = 28.
3.
39 + 6
- Start with 39.
- Add 6 to it: 39 + 6 = 45.
4.
44 + 5
- Start with 44.
- Add 5 to it: 44 + 5 = 49.
5.
59 + 6
- Start with 59.
- Add 6 to it: 59 + 6 = 65.
6.
68 + 3
- Start with 68.
- Add 3 to it: 68 + 3 = 71.
7.
75 + 6
- Start with 75.
- Add 6 to it: 75 + 6 = 81.
8.
88 + 5
- Start with 88.
- Add 5 to it: 88 + 5 = 93.
Final Answer:
1. 24
2. 28
3. 45
4. 49
5. 65
6. 71
7. 81
8. 93
