We used the Jigsaw structure to learn about the instructions for our Bloxels marketing project. There are four parts (logo, app store description, marketing email and commercial). The kids were in their groups, and their "CEO" decided who would do what part. Then they came back together and discussed what they learned. I put 4 QR codes on a piece of paper for them to use at their table.
The first couple hours, it was a little rocky because I didn't realize that none of them had ever done a jigsaw before. After that, I started teaching them the strategy and it worked better. Some of the groups asked questions and discussed things as they worked through, which was not my intent, but worked out fine. Other groups did a traditional jigsaw where they all worked independently and then came back together to share. I thought it was a great strategy and I'll use it again!
