Here are 20 task cards that review properties of addition and multiplication. The cards will review commutative, associative, identity, and distributive properties. I tried to incorporate 4 types of questions that get harder as the number of card increases.
A recording sheet is included as well as an answer key.
This set of task cards has QR codes that the students can scan to check their answers. I find this very helpful to self correct and stay independent. You can download a QR reader app on any smart phone, tablet, or computer with webcam for free.
Here is a link for one:
