Let’s solve each subtraction problem step by step. We’ll count the base ten blocks for each number, write them down, then subtract.
Remember:
- A big square = 100
- A long rod = 10
- A small cube = 1
We’ll go row by row.
---
Row 1:
Left side (first number):
- 5 hundreds → 5 × 100 = 500
- 6 tens → 6 × 10 = 60
- 4 ones → 4 × 1 = 4
→ Total = 500 + 60 + 4 =
564
Right side (second number):
- 3 hundreds → 3 × 100 = 300
- 4 tens → 4 × 10 = 40
- 4 ones → 4 × 1 = 4
→ Total = 300 + 40 + 4 =
344
Now subtract:
564 – 344 = ?
Do it step by step:
- Hundreds: 500 – 300 = 200
- Tens: 60 – 40 = 20
- Ones: 4 – 4 = 0
→ 200 + 20 + 0 =
220
✔ Answer for Row 1:
220

Row 2:
Left side:
- 5 hundreds → 500
- 6 tens → 60
- 3 ones → 3
→ Total = 500 + 60 + 3 =
563
Right side:
- 2 hundreds → 200
- 3 tens → 30
- 2 ones → 2
→ Total = 200 + 30 + 2 =
232
Subtract:
563 – 232 = ?
- Hundreds: 500 – 200 = 300
- Tens: 60 – 30 = 30
- Ones: 3 – 2 = 1
→ 300 + 30 + 1 =
331
✔ Answer for Row 2:
331

Row 3:
Left side:
- 5 hundreds → 500
- 6 tens → 60
- 3 ones → 3
→ Total = 500 + 60 + 3 =
563
Right side:
- 3 hundreds → 300
- 2 tens → 20
- 3 ones → 3
→ Total = 300 + 20 + 3 =
323
Subtract:
563 – 323 = ?
- Hundreds: 500 – 300 = 200
- Tens: 60 – 20 = 40
- Ones: 3 – 3 = 0
→ 200 + 40 + 0 =
240
✔ Answer for Row 3:
240

Row 4:
Left side:
- 4 hundreds → 400
- 3 tens → 30
- 2 ones → 2
→ Total = 400 + 30 + 2 =
432
Right side:
- 2 hundreds → 200
- 3 tens → 30
- 1 one → 1
→ Total = 200 + 30 + 1 =
231
Subtract:
432 – 231 = ?
- Hundreds: 400 – 200 = 200
- Tens: 30 – 30 = 0
- Ones: 2 – 1 = 1
→ 200 + 0 + 1 =
201
✔ Answer for Row 4:
201

Row 5:
Left side:
- 4 hundreds → 400
- 3 tens → 30
- 6 ones → 6
→ Total = 400 + 30 + 6 =
436
Right side:
- 2 hundreds → 200
- 3 tens → 30
- 0 ones → 0
→ Total = 200 + 30 + 0 =
230
Subtract:
436 – 230 = ?
- Hundreds: 400 – 200 = 200
- Tens: 30 – 30 = 0
- Ones: 6 – 0 = 6
→ 200 + 0 + 6 =
206
✔ Answer for Row 5:
206

Final Answer:
Row 1: 220
Row 2: 331
Row 3: 240
Row 4: 201
Row 5: 206
