This week I only had to teach one of my seven 3rd year high school classes, so I didn't want to make some extensive lesson plan for my one class. Typically my students are unmotivated, and about 1/3 of them spend class time sleeping.
I downloaded your PowerPoint and figured it would last the whole class, fearing that it would be too high level, or that the students would just ignore it entirely. It was only going to be for one class, so I figured it would be a good time to experiment.
The students banged it out in about half an hour, and they enjoyed it.
Consequently I had another 15-20 minutes to fill, but by this time the students were engaged. Thank you for a brilliant idea, and bless your immortal soul. :D
