Let's solve the
"Place Value – Three Digit Numbers" worksheet step by step.
We are given abacus representations of three-digit numbers. Each abacus has
three rods:
- The
leftmost rod represents
hundreds,
- The
middle rod represents
tens,
- The
rightmost rod represents
ones (units).
We need to determine the number shown on each abacus based on the number of beads on each rod.

Step-by-step Analysis:
#### 1. First Row:
-
First abacus (given):
- Hundreds: 6 beads → 600
- Tens: 0 beads → 0
- Ones: 3 beads → 3
→ Number =
603 ✔ (already filled)
-
Second abacus (red beads):
- Hundreds: 7 beads → 700
- Tens: 4 beads → 40
- Ones: 1 bead → 1
→ Number =
741
-
Third abacus (yellow beads):
- Hundreds: 5 beads → 500
- Tens: 2 beads → 20
- Ones: 3 beads → 3
→ Number =
523

#### 2. Second Row:
-
Fourth abacus (blue beads):
- Hundreds: 2 beads → 200
- Tens: 8 beads → 80
- Ones: 1 bead → 1
→ Number =
281
-
Fifth abacus (red beads):
- Hundreds: 1 bead → 100
- Tens: 3 beads → 30
- Ones: 7 beads → 7
→ Number =
137
-
Sixth abacus (yellow beads):
- Hundreds: 6 beads → 600
- Tens: 0 beads → 0
- Ones: 9 beads → 9
→ Number =
609
---
#### 3. Third Row:
-
Seventh abacus (blue beads):
- Hundreds: 1 bead → 100
- Tens: 9 beads → 90
- Ones: 6 beads → 6
→ Number =
196
-
Eighth abacus (red beads):
- Hundreds: 3 beads → 300
- Tens: 1 bead → 10
- Ones: 5 beads → 5
→ Number =
315
-
Ninth abacus (yellow beads):
- Hundreds: 2 beads → 200
- Tens: 1 bead → 10
- Ones: 4 beads → 4
→ Number =
214

Final Answers:
Fill in the blanks as follows:
```
Row 1:
603 741 523
Row 2:
281 137 609
Row 3:
196 315 214
```

✔ Answer Summary:
- 741
- 523
- 281
- 137
- 609
- 196
- 315
- 214
These are the missing three-digit numbers based on the place value shown by the abacuses.
