Print task cards out and laminate for use over an over! I print a set for each of my table groups.
Students will be able to practice adding and subtracting fractions with unlike denominators with this QR Code task card set. Once they solve a problem they check themselves using an ipad or iphone by scanning the QR Code.
I use this as an individual review activity. It can be used in centers, small groups, or with partners. My students LOVE this activity because they have the ipad in their hands.
