What’s on this worksheet

Forty three-digit subtraction problems in column form, each requiring at least one borrow. The mix includes regroups across the tens and hundreds, giving children the kind of multi-step borrowing they meet in third grade. Every difference is on the page-2 key.

How to use it

Work right to left, borrowing from the next column whenever the top digit is smaller than the bottom. Have your child rewrite any tricky problem and talk through the borrow — saying it out loud cements the steps.

Aligned to Common Core (3.NBT.A.2)

This worksheet supports Common Core 3.NBT.A.2, where third graders fluently add and subtract within 1,000 using place-value strategies and the standard algorithm.
