Free printable worksheet helping students practice writing 3-digit numbers in expanded form using hundreds, tens, and ones.

The task is to write each number in expanded form using hundreds, tens, and ones.

Expanded form means breaking the number into its place values:
- The first digit (from left) is hundreds
- The second digit is tens
- The third digit is ones

For example:
724 = 7 hundreds + 2 tens + 4 ones

Let’s go one by one:

2) 137 → 1 hundred, 3 tens, 7 ones → 1 hundred + 3 tens + 7 ones
3) 95 → This is only 2 digits. So it’s 0 hundreds, 9 tens, 5 ones → 9 tens + 5 ones
4) 638 → 6 hundreds, 3 tens, 8 ones → 6 hundreds + 3 tens + 8 ones
5) 906 → 9 hundreds, 0 tens, 6 ones → 9 hundreds + 6 ones (we skip “0 tens” since adding zero doesn’t change value)
6) 143 → 1 hundred, 4 tens, 3 ones → 1 hundred + 4 tens + 3 ones
7) 726 → 7 hundreds, 2 tens, 6 ones → 7 hundreds + 2 tens + 6 ones
8) 819 → 8 hundreds, 1 ten, 9 ones → 8 hundreds + 1 ten + 9 ones
9) 67 → 0 hundreds, 6 tens, 7 ones → 6 tens + 7 ones
10) 540 → 5 hundreds, 4 tens, 0 ones → 5 hundreds + 4 tens
11) 658 → 6 hundreds, 5 tens, 8 ones → 6 hundreds + 5 tens + 8 ones
12) 947 → 9 hundreds, 4 tens, 7 ones → 9 hundreds + 4 tens + 7 ones
13) 806 → 8 hundreds, 0 tens, 6 ones → 8 hundreds + 6 ones
14) 430 → 4 hundreds, 3 tens, 0 ones → 4 hundreds + 3 tens
15) 612 → 6 hundreds, 1 ten, 2 ones → 6 hundreds + 1 ten + 2 ones
16) 583 → 5 hundreds, 8 tens, 3 ones → 5 hundreds + 8 tens + 3 ones
17) 947 → Same as #12 → 9 hundreds + 4 tens + 7 ones
18) 302 → 3 hundreds, 0 tens, 2 ones → 3 hundreds + 2 ones
19) 784 → 7 hundreds, 8 tens, 4 ones → 7 hundreds + 8 tens + 4 ones
20) 939 → 9 hundreds, 3 tens, 9 ones → 9 hundreds + 3 tens + 9 ones

Double-checking a few tricky ones:
- 95: no hundreds, so just 9 tens + 5 ones ✔️
- 906: middle digit is 0, so we don’t write “0 tens” — just 9 hundreds + 6 ones ✔️
- 540: last digit is 0, so no “ones” — 5 hundreds + 4 tens ✔️

All look correct.

Final Answer:
2) 1 hundred + 3 tens + 7 ones
3) 9 tens + 5 ones
4) 6 hundreds + 3 tens + 8 ones
5) 9 hundreds + 6 ones
6) 1 hundred + 4 tens + 3 ones
7) 7 hundreds + 2 tens + 6 ones
8) 8 hundreds + 1 ten + 9 ones
9) 6 tens + 7 ones
10) 5 hundreds + 4 tens
11) 6 hundreds + 5 tens + 8 ones
12) 9 hundreds + 4 tens + 7 ones
13) 8 hundreds + 6 ones
14) 4 hundreds + 3 tens
15) 6 hundreds + 1 ten + 2 ones
16) 5 hundreds + 8 tens + 3 ones
17) 9 hundreds + 4 tens + 7 ones
18) 3 hundreds + 2 ones
19) 7 hundreds + 8 tens + 4 ones
20) 9 hundreds + 3 tens + 9 ones
