In this session we played the Al-Jabar game of color-mixing algebra. First we learned how to perform addition and subtraction with colors.

We made several versions of the addition table for colors.

You can see a subgroup of the first four rows and columns, and how it divides the addition table into four quadrants.

If you’re interested, please take a look below at the slides that we used for the activity. Our slides were adapted from the Al-Jabar game web site which you can visit for more ideas and information.
