In my classroom I use interactive whiteboards everyday. The chapter in the section which I really agree with was the idea that interactive whiteboards are a good tool for assisting with classroom management. With math we solve a LOT of problems. Which means there is quite a bit of time required for the teachers/students to write problems - often times meaning you back is to the class. Obviously this is not ideal in terms of classroom management. I have pre-made notes that I bring into the class and use to manage class flow, the problems which are discussed, etc. In other words, all my content is pre-loaded before I walk into the class. Therefore, I am not wasting time trying to remember what I wanted to say, what question/problem to write, etc. Everything is already there for me. In addition, because my students have iPads, I upload my pre-made notes for them to review individually. Therefore, students are able to go at their own pace, especially those that do not lot much explanation.
Along those same lines of classroom management, as I stated, the IWB helps me manage the flow of my class - with everything pre-loaded, I know exactly what I will cover, and where I am going.
