Let's solve each problem on the
Base Ten Blocks worksheet step by step.
---
🔢 Understanding Base Ten Blocks:
-
Green long rods = 10 units (tens)
-
Small green squares = 1 unit (ones)
-
Pink long rods = 10 units (tens)
-
Small pink squares = 1 unit (ones)
We will count the
tens and
ones in each group, then add them together.

→ Total:
14
- Addition:
68 + 14 = 82
✔ Answer: `68 + 14 = 82`
---
✔ Problem 5:
- Left side:
- 5 green rods → 50
- 0 small green squares → 0
→ Total:
50
- Right side:
- 4 green rods → 40
- 2 small green squares → 2
→ Total:
42
- Addition:
50 + 42 = 92
✔ Answer: `50 + 42 = 92`
---
✔ Problem 6:
- Left side:
- 6 pink rods → 60
- 4 small pink squares → 4
→ Total:
64
- Right side:
- 4 pink rods → 40

→ Total:
45
- Addition:
64 + 45 = 109
✔ Answer: `64 + 45 = 109`
---
✔ Problem 7:
- Left side:
- 3 pink rods → 30
- 5 small pink squares → 5
→ Total:
35
- Right side:
- 2 pink rods → 20
- 4 small pink squares → 4
→ Total:
24
- Addition:
35 + 24 = 59
✔ Answer: `35 + 24 = 59`
---
✔ Problem 8:
- Left side:
- 5 green rods → 50
- 7 small green squares → 7
→ Total:
57
- Right side:
- 4 green rods → 40
- 2 small green squares → 2
→ Total:
42
