Created for elementary age students, this is 2 pages of 3-digit subtraction problems set up in a grid with boxes for "regrouping"/"borrowing." The grid format helps students keep their columns lined up, and the boxes will aid them in remembering to "borrow" tens. Use this for homework, as an in-class assessment for students, or as remedial work to help students master the concept of borrowing.
I have also included a blank template in the same grid format so that you are able to make up your own problems if more practice is needed and the format helps your students! :)
An answer key is provided for the 2 pages of problems.
