This set of 20 task cards is designed to support common core standard 7.NS.1, subtracting integers. You can use these task cards two different ways. The first way is the traditional task cards, in which you can use as a whole group, station, review or remediation. The other way is geared to the 21st century learner~QR Codes. There are two student response pages and two answer sheets (traditional and 21st Century). This provides immediate feedback for the students to correct their mistakes.
My students LOVE solving these task cards because they are geared for the 21st century, using QR codes for the problems.
