Optional lesson U1: minimum spanning tree
This lesson was really cool. Kids were interested. Beth's strategy for roll playing bidding (min bid) for a contract to build a router network was spot on. Kids liked this.
This lesson can be pounded out quickly. It could squeeze down to 30 min if the practice problems are given as homework.
I'll definitely do it again and try the other optional lessons.
Also, it's a nice break from the internet simulator.
