The Prezi Response

I was reading a post on The Number Warrior about tilting number lines. The post asks the question, "is the left-to-right number line the best?" The case is made that some see numbers on lines in different ways.  People with synesthesia are notable examples of the phenomena.  The Number Warrior speculated that maybe alternate positioning of the number line may help students learn.  One commenter suggested that students might have a difficult time with that when they started using planes and Cartesian coordinate systems.  I disagreed with the comment and started typing a response and then I thought, "what if I prezi-ed my response?" So that is what I did.  The number line prezi was fun to make and I think it could be a nice conversation starter. I will post about what happens.
