9-11 year olds
This has turned out to be such a relaxing and enjoyable lesson. The kids have been so motivated. Many saying they were going to do more of these tonight.
I have taken the basic lesson a few times in the last few weeks, refining as I go.
Todays refinement was including the rotating square. It involves no formal measuring, therefore appealing to many of the kids.
