Let’s solve each problem step by step.
We are looking at base ten blocks:
- A tall stack of 10 small cubes =
1 ten
- A single small cube =
1 one
We count how many tens and how many ones, then write the number.
---
Problem 1:
- Tens: 1 stack → 10
- Ones: 1 cube → 1
→ Total: 10 + 1 =
11
Problem 2:
- Tens: 3 stacks → 30
- Ones: 5 cubes → 5
→ Total: 30 + 5 =
35
Problem 3:
- Tens: 5 stacks → 50
- Ones: 4 cubes → 4
→ Total: 50 + 4 =
54
Problem 4:
- Tens: 2 stacks → 20
- Ones: Let’s count — there are 8 cubes (two columns of 4)
→ Total: 20 + 8 =
28
Problem 5:
- Tens: 7 stacks → 70
- Ones: Let’s count — 6 cubes in a column, plus 1 more = 7
→ Total: 70 + 7 =
77
Problem 6:
- Tens: 4 stacks → 40
- Ones: Let’s count — 7 cubes (a column of 5, plus 2 more on the right)
→ Total: 40 + 7 =
47
Double-checking all:
1. 1 ten + 1 one = 11
✔
2. 3 tens + 5 ones = 35
✔
3. 5 tens + 4 ones = 54
✔
4. 2 tens + 8 ones = 28
✔
5. 7 tens + 7 ones = 77
✔
6. 4 tens + 7 ones = 47
✔
All correct.
Final Answer:
1. 11
2. 35
3. 54
4. 28
5. 77
6. 47
