After the warm-up exercise we started a game. I marked off a rectangle for our playing board. Then we took turns rolling the dice. If we rolled an odd number, then we had to draw a long-thin rectangle with that number of squares. If we rolled an even number the rectangle was made out of the appropriate number of pairs of two squares side-by-side. The goal was to be the last person able to draw the rectangle dictated by the dice.
We started with four colors of pencil crayon, switching colors whenever we wanted but trying to make sure each shape we drew was distinguishable not blending it with its neighbour. I wondered slightly if we would be able to continue with just the four colors, in accordance with the four color theorem, but my son wasn't strategizing with the colors, we didn't manage to fill the whole space with four colors. Another time I'll make it part of the challenge.
Love it! Thank you for sharing this game with us all. I have an old post you may be interested in checking out. Let me know what you think. How old is your son? We love math games too. http://totplay.blogspot.com/2012/05/skip-counting-area-and-multiplication.html
