PDF | 1 page | Grades: 2 - 3

A resource to help reinforce place value and writing 4-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 4-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 4-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 4-digit number.

This resource allows students to see some of the different combinations that make your 4-digit number. For example, if your number is 3,982, by revealing different gray boxes you can see that it equals:

  • 3,982 ones
  • 398 tens and 2 ones
  • 39 hundreds and 82 ones
  • 39 hundreds 8 tens and 2 ones
  • 3 thousands 982 ones
  • 3 thousands 98 tens and 2 ones
  • 3 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.
