A resource to help reinforce place value and writing 5-digit numbers in expanded form.
Use this resource when teaching students that numbers can be created in a variety of ways and how to write 5-digit numbers in expanded form.
How To Use This Resource:
- Print out a sheet of expanders for each student. Have them cut out each expander.
- On one expander, write a 5-digit number placing each digit in a white box.
- Starting with the first white box, fold the two gray boxes behind it, accordion style. You should now have the first two white boxes side by side.
- Repeat this process for each set of gray boxes. When you are finished, you should only be able to see the white boxes forming your 5-digit number.
This resource allows students to see some of the different combinations that make your 5-digit number. For example, if your number is 43,982, by revealing different gray boxes you can see that it equals:
- 43,982 ones
- 4,398 tens and 2 ones
- 439 hundreds and 82 ones
- 439 hundreds 8 tens and 2 ones
- 43 thousands 982 ones
- 43 thousands 98 tens and 2 ones
- 43 thousands 9 hundreds 8 tens and 2 ones
- 4 ten thousands 3,982 ones
- 4 ten thousands 398 tens and 2 ones
- 4 ten thousands 39 hundreds 82 ones
- 4 ten thousands 39 hundreds 8 tens and 2 ones
- 4 ten thousands 3 one thousands 982 ones
- 4 ten thousands 3 one thousands 98 tens and 2 ones
- 4 ten thousands 3 one thousands 9 hundreds 82 ones
- 4 ten thousands 3 one thousands 9 hundreds 8 tens and 2 ones.
Allow students to use base-10 blocks to model each combination. This resource works well when teaching students this concept in guided math groups.

Common Core Curriculum alignment
Understand that the three digits of a three-digit number represent amounts of hundreds, tens, and ones; e.g., 706 equals 7 hundreds, 0 tens, and 6 ones. Understand the following as special cases:
100 can be thought of as a bundle of ten tens — called a "hundred."
The numbers 100, 200, 300, 400, 500, 600, 700, 800, 900 refer to one, two, three, four, five, six, seven, eight, or nine hundreds (and 0 tens and 0 ones).
Read and write numbers to 1000 using base-ten numerals, number names, and expanded form.
