5-digit number ordering worksheet for math practice.

Let's solve the "Ordering Numbers: 5-Digit" worksheet step by step. The goal is to rewrite each set of numbers in order from least to greatest.

---

a.

Numbers:
12,905 12,509 11,990 21,095 5,925

Step-by-step comparison:

- First, look at the ten-thousands place:
- 12,905 → 1
- 12,509 → 1
- 11,990 → 1
- 21,095 → 2
- 5,925 → 0 (only one digit, so it's less than others)

So 5,925 is the smallest.

Now compare the ones with 1 in the ten-thousands place:
- 11,990 → 1 in ten-thousands, 1 in thousands
- 12,509 → 1 in ten-thousands, 2 in thousands
- 12,905 → 1 in ten-thousands, 2 in thousands

Compare 11,990 vs 12,509 and 12,905:
- 11,990 < 12,509 < 12,905

Then 21,095 is largest.

Order:
5,925 < 11,990 < 12,509 < 12,905 < 21,095

✔ Answer for a:
5,925 11,990 12,509 12,905 21,095

b.

Numbers:
43,677 46,337 4,766 43,776 46,673

Step-by-step:

- Look at the ten-thousands place:
- 43,677 → 4
- 46,337 → 4
- 4,766 → 0 (so it's smaller)
- 43,776 → 4
- 46,673 → 4

So 4,766 is smallest.

Now compare the rest (all start with 4):

- 43,677 → 3 in thousands
- 43,776 → 3 in thousands
- 46,337 → 6 in thousands
- 46,673 → 6 in thousands

So:
- 43,677 vs 43,776: both have 43, compare hundreds:
- 677 vs 776 → 677 < 776 → so 43,677 < 43,776
- 46,337 vs 46,673: both have 46, compare hundreds:
- 337 vs 673 → 337 < 673 → so 46,337 < 46,673

Final order:
4,766 < 43,677 < 43,776 < 46,337 < 46,673

✔ Answer for b:
4,766 43,677 43,776 46,337 46,673

c.

Numbers:
28,213 28,312 23,830 20,833 28,332

Step-by-step:

Look at ten-thousands place: all are 2 or less? Let's check:

- 28,213 → 2
- 28,312 → 2
- 23,830 → 2
- 20,833 → 2
- 28,332 → 2

All start with 2 → now compare thousands place:

- 28,213 → 8
- 28,312 → 8
- 23,830 → 3
- 20,833 → 0
- 28,332 → 8

So:
- 20,833 (thousands = 0) → smallest
- 23,830 (thousands = 3) → next
- Then the three with 8 in thousands: 28,213; 28,312; 28,332

Now compare these:
- All have 28, so compare hundreds place:
- 28,213 → 2
- 28,312 → 3
- 28,332 → 3

So:
- 28,213 (hundreds = 2) → first
- Then 28,312 vs 28,332: both have 3 in hundreds → compare tens:
- 12 vs 32 → 12 < 32 → so 28,312 < 28,332

Final order:
20,833 < 23,830 < 28,213 < 28,312 < 28,332

✔ Answer for c:
20,833 23,830 28,213 28,312 28,332

d.

Numbers:
35,604 53,064 65,064 65,604 36,046

Step-by-step:

Check ten-thousands place:

- 35,604 → 3
- 53,064 → 5
- 65,064 → 6
- 65,604 → 6
- 36,046 → 3

So group:
- 35,604 and 36,046 → both start with 3
- 53,064 → 5
- 65,064 and 65,604 → both start with 6

So order of groups: 3s < 5s < 6s

Now within 3s:
- 35,604 vs 36,046
- Both have 3 in ten-thousands
- Compare thousands: 5 vs 6 → 5 < 6 → so 35,604 < 36,046

Next: 53,064

Then 65,064 vs 65,604:
- Both have 65 → compare hundreds: 0 vs 6 → 0 < 6 → so 65,064 < 65,604

Final order:
35,604 < 36,046 < 53,064 < 65,064 < 65,604

✔ Answer for d:
35,604 36,046 53,064 65,064 65,604
