These QR cards for three digit addition and subtraction can be used for whole group or small group activities. Place each card at a desk and have students rotate, use at the small group table, or print off some sets and put on rings for students to flip through in their center bins.
Get the best use out of these by printing on cardstock, cutting each card, and then laminating.
This set comes in both black in white and color addition as well as subtraction. Print on white or colored paper. All sets have a mix of problems (with and without regrouping). Each set also includes a page for students to show their work (you could print however many you want off and laminate for continual use).
18 cards for addition and 18 cards for subtraction
Makes for a great math center-- just punch a hole in the corner of each and put on a binder ring!
