Let’s go through each problem one by one. We’re counting base ten blocks:
- Tall yellow rods =
tens (each rod is 10)
- Small yellow cubes =
ones (each cube is 1)
We’ll count the tens and ones for each number, then write the total.
---
Problem 1:
- Tens: 1 rod → 10
- Ones: 1 cube → 1
→ Total: 10 + 1 =
11
Problem 2:
- Tens: 3 rods → 3 × 10 = 30
- Ones: 5 cubes → 5
→ Total: 30 + 5 =
35
Problem 3:
- Tens: 5 rods → 5 × 10 = 50
- Ones: 4 cubes → 4
→ Total: 50 + 4 =
54
Problem 4:
- Tens: 2 rods → 2 × 10 = 20
- Ones: Let’s count the small cubes — there are 8 cubes (arranged in two columns of 4) → 8
→ Total: 20 + 8 =
28
Problem 5:
- Tens: 7 rods → 7 × 10 = 70
- Ones: 6 cubes → 6
→ Total: 70 + 6 =
76
Problem 6:
- Tens: 4 rods → 4 × 10 = 40
- Ones: Let’s count — 7 cubes (one column of 5, plus 2 more on the right) → 7
→ Total: 40 + 7 =
47
