Just in time for the superbowl! This download includes 12 task cards each with a two-digit subtraction number sentence and QR code. Students copy the number sentence onto their recording sheet, solve, and check their answer by scanning the QR code. If their answer is correct, they shade in "Touchdown." If their answer is incorrect, students shade in "miss." I suggest printing task cards onto card stock, laminating, and using in a math center. Recording sheet and answer sheet are included for accountability and easy grading! Enjoy!
