Order 3-digit numbers - Number and Place Value by URBrainy.com - Free Printable

Let's solve the problem step by step.

The task is to order 3-digit numbers from smallest to largest, starting with the smallest. We’ll go through each row one by one.

---

Row 1:

Numbers:
396, 277, 369, 727, 693, 772

Let’s compare them:

- Start with the hundreds digit:
- 277 → 2 (smallest)
- 369 → 3
- 396 → 3
- 693 → 6
- 727 → 7
- 772 → 7

Now order by hundreds digit:
- 277 (2)
- 369 and 396 (both 3s) → compare tens:
- 369 → 6 tens
- 396 → 9 tens → so 369 < 396
- Then 693 (6)
- Then 727 and 772 (both 7s): 727 vs 772 → 727 < 772

So ordered:
277, 369, 396, 693, 727, 772

Row 2:

Numbers:
205, 214, 277, 209, 240, 210

All start with 2 → look at tens digit:

- 205 → 0 tens
- 209 → 0 tens → compare units: 5 < 9 → 205 < 209
- 210 → 1 ten
- 214 → 1 ten → 10 < 14 → 210 < 214
- 240 → 4 tens
- 277 → 7 tens

Ordering:
- 205, 209 (both 20x)
- 210, 214 (both 21x)
- 240
- 277

So:
205, 209, 210, 214, 240, 277

Row 3:

Numbers:
444, 404, 440, 414, 441, 144

Hundreds digits:
- 144 → 1 (smallest)
- Others are all 4s

So 144 is first.

Now the rest (all 4xx):
- 404 → 0 tens
- 414 → 1 ten
- 440 → 4 tens
- 441 → 4 tens
- 444 → 4 tens

Compare:
- 404 (0 tens)
- 414 (1 ten)
- 440, 441, 444 → same tens digit (4), so compare units:
- 440 → 0
- 441 → 1
- 444 → 4

So: 440 < 441 < 444

Full order:
144, 404, 414, 440, 441, 444

Row 4:

Numbers:
678, 786, 867, 876, 687, 768

Hundreds digits:
- 678 → 6
- 687 → 6
- 768 → 7
- 786 → 7
- 867 → 8
- 876 → 8

Group by hundreds:
- 600s: 678, 687 → compare tens:
- 678 → 7 tens
- 687 → 8 tens → so 678 < 687
- 700s: 768, 786 → tens:
- 768 → 6 tens
- 786 → 8 tens → 768 < 786
- 800s: 867, 876 → tens:
- 867 → 6 tens
- 876 → 7 tens → 867 < 876

So full order:
678, 687, 768, 786, 867, 876

---

Row 5:

Numbers:
523, 235, 532, 325, 253, 352

Hundreds digits:
- 235 → 2
- 253 → 2
- 325 → 3
- 352 → 3
- 523 → 5
- 532 → 5

Group:
- 200s: 235, 253 → tens:
- 235 → 3 tens
- 253 → 5 tens → 235 < 253
- 300s: 325, 352 → tens:
- 325 → 2 tens
- 352 → 5 tens → 325 < 352
- 500s: 523, 532 → tens:
- 523 → 2 tens
- 532 → 3 tens → 523 < 532

So order:
235, 253, 325, 352, 523, 532
