The image is an
Abacus Counting Worksheet designed to help students practice reading numbers from an abacus. Each abacus has two rods: one for
Tens and one for
Ones, with beads representing digits.
---
🔍 How to Read the Abacus:
- The
left rod represents
Tens.
- The
right rod represents
Ones.
- Each bead on a rod represents 1 unit.
- Beads are typically moved toward the center (or top) to represent value.
- In this worksheet,
blue beads are used to indicate counted values.
We will go through each abacus and determine the number represented by counting the beads in the
Tens and
Ones columns.

✔ Step-by-step Analysis:
#### 1. First Row:
1.
Abacus 1:
- Tens: 5 blue beads → 5 × 10 =
50
- Ones: 1 gray bead (but not colored, likely just a placeholder or inactive) → 0
-
Total = 50
2.
Abacus 2:
- Tens: 1 blue bead → 1 × 10 =
10
- Ones: 2 pink beads → 2
-
Total = 12
3.
Abacus 3:
- Tens: 7 blue beads → 7 × 10 =
70
- Ones: 1 gray bead → 0
-
Total = 70

#### 2. Second Row:
4.
Abacus 4:
- Tens: 3 blue beads → 3 × 10 =
30
- Ones: 0 beads → 0
-
Total = 30
5.
Abacus 5:
- Tens: 3 blue beads → 3 × 10 =
30
- Ones: 0 beads → 0
-
Total = 30
6.
Abacus 6:
- Tens: 4 blue beads → 4 × 10 =
40
- Ones: 9 gray beads (likely 9 ones) → 9
-
Total = 49
---
#### 3. Third Row:
7.
Abacus 7:
- Tens: 8 blue beads → 8 × 10 =
80
- Ones: 0 beads → 0
-
Total = 80
8.
Abacus 8:
- Tens: 1 blue bead → 1 × 10 =
10
- Ones: 8 gray beads → 8
-
Total = 18
9.
Abacus 9:
- Tens: 2 blue beads → 2 × 10 =
20
- Ones: 1 gray bead → 1
-
Total = 21
