How to teach this

Say the number in place value language before writing: 358 is "three hundreds, five tens, eight ones." Then write each value as its own number and read the sum back. If your child writes 3 + 5 + 8, build the number with base-ten blocks and count what each pile is really worth.

Watch for: Kids write 358 as 3 + 5 + 8. Each digit stands for its place value, so it's 300 + 50 + 8. Kids skip an empty place and read 4,000 + 90 + 6 as 496. The missing hundreds still needs a zero, so it's 4,096.

Common questions about expanded form

What is expanded form for 2nd grade?

It's writing a number as the sum of its place values, like 358 = 300 + 50 + 8. These sheets practice both writing the expanded form and adding the parts back together.

Why does my child write 358 as 3 + 5 + 8?

They're reading the digits without their places yet. Regular practice expanding numbers, ideally next to base-ten blocks, fixes this quickly.
