Let's solve the abacus worksheet step by step.
Understanding the Abacus:
- Each abacus has two columns:
-
T = Tens place
-
O = Ones place
- Beads above the bar (usually one) represent
5, and beads below represent
1.
- However, in this worksheet, it appears that
each bead is worth 1, and we're just counting the number of beads in each column.
We'll count the beads in the
Tens (T) and
Ones (O) places for each abacus and write the total value.

Step-by-step Counting:
####
Row 1:
1.
Abacus 1:
- Tens (T): 1 bead → 10
- Ones (O): 4 beads → 4
- Total:
14
2.
Abacus 2:
- Tens (T): 2 beads → 20
- Ones (O): 3 beads → 3
- Total:
23
3.
Abacus 3:
- Tens (T): 1 bead → 10
- Ones (O): 6 beads → 6
- Total:
16
4.
Abacus 4:
- Tens (T): 1 bead → 10
- Ones (O): 7 beads → 7
- Total:
17

- Total:
13
10.
Abacus 10:
- Tens (T): 3 beads → 30
- Ones (O): 7 beads → 7
- Total:
37
11.
Abacus 11:
- Tens (T): 5 beads → 50
- Ones (O): 5 beads → 5
- Total:
55
12.
Abacus 12:
- Tens (T): 2 beads → 20
- Ones (O): 6 beads → 6
- Total:
26

✔ Final Answers:
Fill in the blanks with the following numbers:
```
14 23 16 17
42 13 34 29
13 37 55 26
```

🔍 Explanation:
- For each abacus, we counted how many beads are in the
Tens column and multiplied by 10.
- Then counted the
Ones column.
- Added both values to get the total number represented.
This helps students understand
place value (tens and ones) using a visual tool — the abacus.
