Some things stood out: I talk to much (lol), and I am not taking as much care as to where I present the task & how as maybe I should be. Also, KG is best in groups of 2.
We have been reading a page or two of Greg Tang's Matherpeices weekly. On this day we read & solved the page on Piet Mondrian. We also watched a video on Mondrian (you can get alot of milage out of his books). Then I placed the students at workstations and told them that there was a painter who wanted to paint a picture with 7 coloured rectangles. Some rectangles were blue, some rectangels were red, and some rectangles were yellow. How may different ways could he paint his 7 coloured rectangles?
Then I gave groups a bunch of coloured rectangles.
