Sketchometry is another intriguing approach to interactive mathematics, especially on touch devices. I’ve tried it out a little bit on my iPad, and while there is some learning curve, I was able to graph some functions and draw a bit.
I am particularly interested in the touch aspect of the program. Bringing the kinetic into mathematics is something a teacher can do in class if he or she thinks about it, but it is not something that is well-transmitted through a book. I (Kaisa) tend to understand some mathematical concepts best visually and kinetically. Innovative touch interfaces to math exploration programs appeal a lot!
Anyone else tried Sketchometry?
