Day 5 of the program. Today, when I taught math classes, I had an unusually high degree of mental clarity and sense of rhythm in my presentation. Overall, my students tracked very well with the material. Topics covered were graphical in nature, so one hopes that students will make a connection between the mathematical expressions and the graphs they are drawing. That connection was made by nearly all the students. The instructional material was of high quality, and both the students and I made good use of it-more successfully than I have ever seen. Even when there was some confusion along the way, they completed the in-class exercises with little anxiety.
