These tasks cards were created to be used as a scoot or walk around the room and solve. Each card has an input/output chart with missing values. Students will find the missing values. There are some cards where the values are not missing. In this case, the students have to find out what the rule is on the chart. The QR codes provide a self checking element so students can check themselves. There is an editable page where you can create your own cards. There is also an answer sheet that has all of the QR codes on one page to see the answers. Lastly, there is a student recording sheet.
