I will pass out the jigsaw cards and call a group based on shape, letter, color, etc. Students will get into their respective groups and begin the discussion/activity. If and when I want them to regroup, I'll call out a new sorting rule and the students can look at their cards and find their new groups. I wanted to add more detail to the cards, but MS Office wasn't cooperating well with me this morning. I left a few blank cards at the end, so you can make your own cards if you'd like! I made a set of 22 jigsaw cards and you are welcome to them! Click here for the jigsaw cards!
