This file contains a set of 24 task cards with QR Codes so students will be able to check their answers. There is a set of addition and subtraction using both 2 digits and 3 digits. (with a Fall Theme). There is also four bonus practice sheets. Recording sheets and Answer Keys are included for all. These would be great for third grade but would be a good practice resource for others.
Task cards can be used in small groups or in a center. Print, cut out and laminate.
To use the QR code: Have students write their answers on the recording sheet provided, and then they can scan the QR code to check their answers. An electronic device, like an I-pad is needed to read the codes.
