Let’s go through each problem one by one. We’re counting base ten blocks — the tall rods are “tens” (each = 10), and the small cubes are “ones” (each = 1).
We’ll count tens first, then ones, add them together, write the number in numerals, and then write it out in words.
---
Top Row, Left:
- Tens: 3 rods → 3 × 10 = 30
- Ones: 4 cubes → 4
- Total: 30 + 4 =
34
- In words:
thirty-four
---
Top Row, Middle:
- Tens: 5 rods → 5 × 10 = 50
- Ones: 1 cube → 1
- Total: 50 + 1 =
51
- In words:
fifty-one
---
Top Row, Right:
- Tens: 2 rods → 2 × 10 = 20
- Ones: 7 cubes → 7
- Total: 20 + 7 =
27
- In words:
twenty-seven
---
Middle Row, Left:
- Tens: 6 rods → 6 × 10 = 60
- Ones: 2 cubes → 2
- Total: 60 + 2 =
62
- In words:
sixty-two
---
Middle Row, Middle:
- Tens: 8 rods → 8 × 10 = 80
- Ones: 4 cubes → 4
- Total: 80 + 4 =
84
- In words:
eighty-four
---
Middle Row, Right:
- Tens: 9 rods → 9 × 10 = 90
- Ones: 0 cubes → 0
- Total: 90 + 0 =
90
- In words:
ninety
---
Bottom Row, Left:
- Tens: 4 rods → 4 × 10 = 40
- Ones: 7 cubes → 7
- Total: 40 + 7 =
47
- In words:
forty-seven
---
Bottom Row, Middle:
- Tens: 6 rods → 6 × 10 = 60
- Ones: 6 cubes → 6
- Total: 60 + 6 =
66
- In words:
sixty-six
---
Bottom Row, Right:
- Tens: 1 rod → 1 × 10 = 10
- Ones: 1 cube → 1
- Total: 10 + 1 =
11
- In words:
eleven

Final Answer:
34 (thirty-four), 51 (fifty-one), 27 (twenty-seven),
62 (sixty-two), 84 (eighty-four), 90 (ninety),
47 (forty-seven), 66 (sixty-six), 11 (eleven)
