MotionMath for iPod & iPad - #edchat #edtech

My west-coast, school-administrator cousin encouraged me to check out MotionMath.  It seems to be an early version (i.e. there is no menu, or at least I couldn't find it!) but I have been extremely impressed by its design.  Users are required to land a bouncing ball at the approximate subdivision provided by the program.  For example, if given 1/3, you have to try and land the ball 1/3 of the way between the 0 and 1.

The most impressive feature is the scaled feedback which the program provides when mistakes are made.  On the first "mis-bounce",  an arrow appears below the number line to indicate where the ball should land.  On the second miss, sub-divisions are displayed on the number line.  On the third miss, all but the correct fraction subdivision appear on the number line.

I think that the developers have done a great job with this app and I'm curious to see where it goes from here.
