Created for elementary age students, this is 4 pages of addition and subtraction problems set up in a grid with boxes for "regrouping"/"carrying"/"borrowing." The grid format helps students keep their columns lined up, and the boxes will aid them in remembering to "carry" or "borrow" tens. Use this for homework or as an in-class assessment for students.
Updated to include answer keys! :)
