Write 381 in expanded form

1 Show it with blocks

381 is 3 hundreds, 8 tens, 1 one.

2 Put the digits in the chart

Each digit has a place.

3 Find the value of each digit

The 3 is 3 hundreds.

That is 300.

The 8 is 8 tens.

That is 80.

The 1 is 1 one.

That is 1.

4 Write it as a sum

Expanded form means we write the value of each digit, with + between them.

381 = 300 + 80 + 1

5 Check

We add them back: 300 and 80 and 1 make 381.

Yes!

It works.

300 + 80 + 1 = 381
