So. I have a working app that will do the three things I wish it to do on a horizontal number line. I can let the student slide a slide bar back and forth to “see” subtraction on a number line. I can present the student with an equation on the number line and ask […]

Overhearing a discussion of why student can’t get the math.  Friend says, “that’s why you’re not getting it! You have to go in order!”  But… she’s getting some right, then when moves forward, can’t apply.   Then: “Can’t remember all the rules!”       Couple things seem to be happening:   “getting it” is defined […]

I’m impressed with the software and the response/customer service. Okay, it doesn’t have a whiteboard so I can’t actually draw out stuff … but that just inspires me to give that Livescribe thing another shot.
