I found a neat pattern made with trapezoids, squares, and rectangles, and since we are doing Geometry I thought we might try it out. I have four kids per group, 5 groups right now. I was thinking of having each group do one square and then try and put it together using other geometric figures. Of course none of us know how to do this but a local friend has offered to come in and help out if needed.
