You don't know my little brother as the bothersome sibling who always got me in trouble until he finally grew up into the super cool guy that he is today. You probably know Justin more from the MathTacular and Discover & Do fame.
[Speaking of MathTacular, you can now officially and publicly Like MathTacular on Facebook. <hint, hint>]
In honor of Justin's birthday, I'd love it if you'd share your favorite Justin Memory. Which activity from MathTacular or Discover & Do* is your favorite?
I'd have to say the activities with Commutative Man are my favorites. But that's probably more self-serving than anything. <smile>
