Let's solve each problem step by step using
place value blocks:
- A
large blue square represents
100 blocks (hundreds).
- A
green rod (tall rectangle) represents
10 blocks (tens).
- A
small orange cube represents
1 block (ones).
We'll count the total number of blocks for each set.
---
1)
- 1 large blue square = 100
- 3 green rods = 3 × 10 = 30
- 0 small cubes
✔ Total:
100 + 30 = 130
---
2)
- 2 large blue squares = 2 × 100 = 200
- 0 green rods
- 4 small cubes = 4
✔ Total:
200 + 4 = 204
---
3)
- 1 large blue square = 100
- 4 green rods = 4 × 10 = 40
- 7 small cubes = 7
✔ Total:
100 + 40 + 7 = 147
---
4)
- 2 large blue squares = 2 × 100 = 200
- 1 green rod = 10
- 2 small cubes = 2
✔ Total:
200 + 10 + 2 = 212
---
5)
- 3 large blue squares = 3 × 100 = 300
- 0 green rods
- 5 small cubes = 5
✔ Total:
300 + 5 = 305
---
6)
- 2 large blue squares = 2 × 100 = 200
- 6 green rods = 6 × 10 = 60
- 0 small cubes
✔ Total:
200 + 60 = 260
---
7)
- 4 large blue squares = 4 × 100 = 400
- 4 green rods = 4 × 10 = 40
- 6 small cubes = 6
✔ Total:
400 + 40 + 6 = 446
---
8)
- 5 large blue squares = 5 × 100 = 500
- 2 green rods = 2 × 10 = 20
- 3 small cubes = 3
✔ Total:
500 + 20 + 3 = 523
---
✔ Final Answers:
1)
130
2)
204
3)
147
4)
212
5)
305
6)
