Factoring Dice

via Kaleb Allinson

I play a game in class called guess my dice right before we do factoring. I made this up when I taught a low level Algebra 2 class. I roll two dice that have more than six sides. (I started with six siders and then very quickly went to a local game store and bought some 8,10, and 12 sided dice.)
I tell my students that my dice add to 19 and multiply to 88 and ask them to guess my dice. I try to play this at the end of class for a week or two as I have time leading up to factoring. Then when they discover how to factor this dice guessing skill is very helpful. They always realize what I’ve done and think I’m really tricky.
