## Understanding Four-Digit Place Value by Expanding Numbers

This place value number expander gives your students the tactile experience they need to expand 4-digit numbers physically. These expander templates have been a staple in many classrooms to help students understand place value and the correct way to read and write 4-digit numbers.

**How To Use This Resource**

- Print out a sheet of expanders for each student. Have them cut out each expander.
- Write a 4-digit number on one expander, 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 3-digit number.

This resource allows students to see some of the different combinations that make your 4-digit number. For example:

- 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 maths groups.
