Created for elementary age students, this is 4 pages of 2-digit 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. SOME problems do not require regrouping in order to keep students on their toes about the process of decided whether to regroup! I've also included a blank template for both addition and subtraction so that you can make more practice worksheets for your students using the same format! Use this for homework, as a teaching aid, or as an in-class assessment for students. Updated to include answer keys! :) Updated 12/2019 to include blank templates :) Updated 2/2021 to include Google Slides versions for remote learning and updated clipart :) Check out these other popular double digit products that I offer in my shop: Double Digit Addition & Subtraction 1 Double Digit Thanksgiving Jokes Double Digit Spring Jokes
