Boredom attacks!

I just finished giving the first semester exams this past Friday, so I've been very busy. However, I did notice something about myself when I was doing the exam review for my 3 functions and modeling classes: I discovered that I was bored. I make my math exam reviews as animated PowerPoint slide shows and tweak them from one year to the next; hence, there was nothing new in them for me. Plus the said 3 classes I teach in a row (periods 2, 3, and 4 to be precise), so I guess that going over the same stuff in the same way 3 times in a row just bored me silly. I am thinking this over because I realized that I've probably been unconsciously bored all along. It's definitely time to put some spice into my teaching!
