I have always been a fan of PowerPoint and I have seen its use in many non-math classes. However, I never considered its use in a math classroom until recently. For one of my classes, I did a group presentation about the disadvantages and advantages about PowerPoint. During my research for this presentation, I came across an article entitled "Life after death by PowerPoint" by Jenni Ingram. According to Ingram, PowerPoint can be used in math in the following ways:
1) Various colors can be used to show the difference in steps, parts of a drawing, etc.
2) Animation can be used to show the progression of mathematical thought.
3) Hyperlinks can be used to access interactive websites and even other PowerPoint slides that contain alternate explanations for a math problem.
One of my classmates created a color coded geometry proof in PowerPoint that I believe would be very useful in a geometry classroom.
I am now convinced that PowerPoint is a great tool to use in a mathematics classroom.

According to a recent personal communication with a special education specialist, a simple PowerPoint slide or two in a math classroom displaying directions or relevant information to the day's lesson can be very helpful for students with learning disabilities.
What are your thoughts about PowerPoint in a math classroom?
