Teaching Tumbling Tiles

So I taught the Tumbling Tiles lesson to middle schoolers today. Big class, but I noticed one section of boys was really getting into it, making geometric designs...

















After class, they went outside, and their teacher called me out to see.... those same four boys were putting their tiles together to make a big collaborative piece, spontaneously--nobody told them to do this, they just understood the lesson. Whoo-hooo!





















Thanks guys!
