Expanded Form - Ten Thousands

This lesson is about writing numbers to ten thousands in expanded form.

First, you will copy the worksheet so that each student will have a copy.

Then, you will write draw a chart on the board to show the students what they will do on their worksheet.

For the number 31,457, you can draw a chart to show:

Ten Thousands Thousands Hundreds Tens Ones

Then, you will place the numbers in the right place value.

3 1 4 5 7

The value of the 3 is 30,000. There are 3 ten thousands, which equals 30,000

The value of the 1 is 1,000. There are 1 thousand, which equals 1,000.

The value of the 4 is 400. There are 4 hundreds, which equals 400.

The value of the 5 is 50. There are 5 tens, which equals 50.

The value of the 7 is 7. There are 7 ones, which equals 7.

Expanded form of 31,457 = 30,000 + 1,000 + 400 + 50 + 7

After that, you will pass out the worksheet so they can work on them independently.
