I taught this lesson with my CIS class. It went well, although some of the content was a little uneasy for some, but it went over well. The conversation from the group discussing the different four parts got very in depth. It brought up a lot of conversations about slavery. The math software was a little difficult for some to grasp, but I let them play on it to find out how to design their own braids. I thought about bringing in rope and having them plait the rope and discuss the steps of plaiting. I need another activity to add to this lesson that will help put more of the problem solving aspect into the lesson.
