The RAFT technique is described here.
This RAFT has been prepared for Relations and Functions. Print the document below, and cut it into strips. Have each student select one slip and begin preparing it. I usually let them re-draw if they get one they absolutely hate.
I don’t put many stipulations on what I expect in their submission, other than it needs to show me some understanding. I will quite often let them work on these in pairs.
