Expanded form across the grades

2nd grade

Expanded form worksheets ask 2nd graders to stretch a three-digit number into its place values (358 becomes 300 + 50 + 8), and to add the parts back into a single number.

3rd grade

By 3rd grade, expanded form moves to four-digit numbers, including tricky ones with internal zeros: 4,096 is 4,000 + 90 + 6, with no hundreds part to write. These worksheets practice both expanding and composing.
