Let's solve each problem step by step using
base ten blocks, where:
- A
large cube represents
1,000 (thousands),
- A
flat square represents
100 (hundreds),
- A
long rod represents
10 (tens),
- A
small cube represents
1 (ones).
We'll count the number of each block and write the total number.
---
1)
-
Thousands: 3 large cubes → 3 × 1,000 =
3,000
-
Hundreds: 8 flat squares → 8 × 100 =
800
-
Tens: 9 rods → 9 × 10 =
90
-
Ones: 8 small cubes → 8 × 1 =
8
Add them:
3,000 + 800 + 90 + 8 =
3,898
✔ Answer: 3,898

2)
-
Thousands: 5 large cubes → 5 × 1,000 =
5,000
-
Hundreds: 3 flat squares → 3 × 100 =
300
-
Tens: 6 rods → 6 × 10 =
60
-
Ones: 8 small cubes → 8 × 1 =
8
Add them:
5,000 + 300 + 60 + 8 =
5,368
✔ Answer: 5,368

3)
-
Thousands: 2 large cubes → 2 × 1,000 =
2,000
-
Hundreds: 4 flat squares → 4 × 100 =
400
-
Tens: 7 rods → 7 × 10 =
70
-
Ones: 2 small cubes → 2 × 1 =
2
Add them:
2,000 + 400 + 70 + 2 =
2,472
✔ Answer: 2,472

4)
-
Thousands: 4 large cubes → 4 × 1,000 =
4,000
-
Hundreds: 5 flat squares → 5 × 100 =
500
-
Tens: 5 rods → 5 × 10 =
50
-
Ones: 3 small cubes → 3 × 1 =
3
Add them:
4,000 + 500 + 50 + 3 =
4,553
✔ Answer: 4,553

5)
-
Thousands: 1 large cube → 1 × 1,000 =
1,000
-
Hundreds: 6 flat squares → 6 × 100 =
600
-
Tens: 9 rods → 9 × 10 =
90
-
Ones: 9 small cubes → 9 × 1 =
9
Add them:
1,000 + 600 + 90 + 9 =
1,699
✔ Answer: 1,699
