Each task card comes with a QR code that students can scan on iPads, phones or computers. The QR code immediately pulls up the answer and the work that accompanies that answer. Students can check their work and if they made a mistake, they can use the work to figure out where they went wrong.
This version contains 20 task cards designed for Years 5 and 6. In my class, I print these off and use them in small group. While I'm working with a group of students on a particular skills, I have a couple other small groups working on task cards in which they are writing out the answers and using an iPad to scan the QR code. My colleague across the hall uses her Chromebooks to scan the codes. These cards allow the groups to be self sufficient in making sure that they are practicing correctly.
