Ordering decimals worksheet for Grade 4 students, focusing on arranging decimal numbers in ascending order.

Let's solve the "Ordering Decimals" worksheet step by step. The task is to write the numbers from smallest to largest for each group.

1) Group 1:

Numbers:
58.4, 30.2, 54.4, 4.86, 13.1, 53.7, 16.83, 4.06, 13.09, 12.73, 76.3, 31.29, 45.5, 39.2

#### Step-by-step:
- First, look at the whole number part (before the decimal).
- Then compare the decimal parts if needed.

List them in order:

Start with the smallest whole number:
- 4.06, 4.86 → both have whole number 4
- Compare decimals: 4.06 < 4.86
- Next: 12.73, 13.09, 13.1 → all start with 13
- 12.73 < 13.09 < 13.1
- Then: 16.83
- Then: 23.6? Wait — no, we don't have 23.6. Let’s list all again.

Actually, let's sort properly:

| Number | Whole Part |
|--------|------------|
| 4.06 | 4 |
| 4.86 | 4 |
| 12.73 | 12 |
| 13.09 | 13 |
| 13.1 | 13 |
| 16.83 | 16 |
| 30.2 | 30 |
| 31.29 | 31 |
| 39.2 | 39 |
| 45.5 | 45 |
| 53.7 | 53 |
| 54.4 | 54 |
| 58.4 | 58 |
| 76.3 | 76 |

Now order by whole number, then decimal:

1. 4.06
2. 4.86
3. 12.73
4. 13.09
5. 13.1
6. 16.83
7. 30.2
8. 31.29
9. 39.2
10. 45.5
11. 53.7
12. 54.4
13. 58.4
14. 76.3

✔ Final order:
4.06, 4.86, 12.73, 13.09, 13.1, 16.83, 30.2, 31.29, 39.2, 45.5, 53.7, 54.4, 58.4, 76.3

2) Group 2:

Numbers:
3.33, 3.76, 35.51, 337.17, 34.2

All are positive decimals.

Look at whole parts:
- 3.33 → 3
- 3.76 → 3
- 34.2 → 34
- 35.51 → 35
- 337.17 → 337

So:
- 3.33 and 3.76 → compare decimals: 3.33 < 3.76
- Then 34.2
- Then 35.51
- Then 337.17

✔ Order:
3.33, 3.76, 34.2, 35.51, 337.17

---

3) Group 3:

Numbers:
10.28, 24.7, 129.7, 40.89, 66.4

Whole parts:
- 10.28 → 10
- 24.7 → 24
- 40.89 → 40
- 66.4 → 66
- 129.7 → 129

So order:
- 10.28
- 24.7
- 40.89
- 66.4
- 129.7

✔ Order:
10.28, 24.7, 40.89, 66.4, 129.7

4) Group 4:

Numbers:
37.69, 25.51, 34.46, 36.40, 85.2

Whole parts:
- 25.51 → 25
- 34.46 → 34
- 36.40 → 36
- 37.69 → 37
- 85.2 → 85

Order:
- 25.51
- 34.46
- 36.40
- 37.69
- 85.2

✔ Order:
25.51, 34.46, 36.40, 37.69, 85.2

---

5) Group 5:

Numbers:
10.17, 5.7, 55.7, 10.21, 53.87

Whole parts:
- 5.7 → 5
- 10.17 → 10
- 10.21 → 10
- 53.87 → 53
- 55.7 → 55

Now:
- 5.7 (smallest)
- Then 10.17 and 10.21 → compare decimals: 10.17 < 10.21
- Then 53.87
- Then 55.7

✔ Order:
5.7, 10.17, 10.21, 53.87, 55.7

Numbers:
121.6, 17.1, 103.10, 189.6, 28.50

Whole parts:
- 17.1 → 17
- 28.50 → 28
- 103.10 → 103
- 121.6 → 121
- 189.6 → 189

Order:
- 17.1
- 28.50
- 103.10
- 121.6
- 189.6

✔ Order:

🔍 Explanation:

To order decimals:
1. Compare whole number parts first.
2. If whole parts are equal, compare the decimal parts digit by digit.
3. Remember: more digits after decimal doesn’t mean larger value — e.g., 10.17 < 10.21 even though 10.21 has fewer digits.

This method ensures accurate ordering of decimals.
