Let's solve this step by step. The worksheet asks you to
write the number that each set of base 10 blocks represents. Base 10 blocks use:
-
Long rods =
tens (each rod = 10)
-
Small cubes =
ones (each cube = 1)
We’ll go through each problem and count the tens and ones.
---
1.
-
Tens: 1 rod → 10
-
Ones: 3 small cubes → 3
-
Number: 10 + 3 =
13
> Tens: 1, Ones: 3
---
2.
-
Tens: 3 rods → 30
-
Ones: 5 small cubes → 5
-
Number: 30 + 5 =
35
> Tens: 3, Ones: 5
---
3.
-
Tens: 5 rods → 50
-
Ones: 1 small cube → 1
-
Number: 50 + 1 =
51
> Tens: 5, Ones: 1
---
4.
-
Tens: 2 rods → 20
-
Ones: 7 small cubes → 7
-
Number: 20 + 7 =
27
> Tens: 2, Ones: 7
---
5.
-
Tens: 4 rods → 40
-
Ones: 0 small cubes → 0
-
Number: 40 + 0 =
40
> Tens: 4, Ones: 0
---
6.
-
Tens: 5 rods → 50
-
Ones: 4 small cubes → 4
-
Number: 50 + 4 =
54
> Tens: 5, Ones: 4
---
7.
-
Tens: 6 rods → 60
-
Ones: 0 small cubes → 0
-
Number: 60 + 0 =
60
> Tens: 6, Ones: 0
---
8.
-
Tens: 1 rod → 10
-
Ones: 8 small cubes → 8
-
Number: 10 + 8 =
18
> Tens: 1, Ones: 8
---
9.
-
Tens: 2 rods → 20
-
Ones: 1 small cube → 1
-
Number: 20 + 1 =
21
> Tens: 2, Ones: 1
---
10.
-
Tens: 0 rods → 0
-
Ones: 7 small cubes → 7
-
Number: 0 + 7 =
7
> Tens: 0, Ones: 7
---
✔ Final Answers:
| Problem | Tens | Ones | Number |
|--------|------|------|--------|
| 1 | 1 | 3 | 13 |
| 2 | 3 | 5 | 35 |
| 3 | 5 | 1 | 51 |
| 4 | 2 | 7 | 27 |
| 5 | 4 | 0 | 40 |
| 6 | 5 | 4 | 54 |
| 7 | 6 | 0 | 60 |
| 8 | 1 | 8 | 18 |
| 9 | 2 | 1 | 21 |
| 10 | 0 | 7 | 7 |
You would write these numbers in the corresponding "tens" and "ones" boxes on the worksheet.
