Hello Nicholas...have you done the SUBTRACTION version?
If not, I am on it! I am not teaching in a classroom right now, but this is what makes me want to go back!!!!!!!
I would have the students creating these type of "critical thinking" demonstrations for all of the algorithms they use (Pythagorean Theorem, Quadratic Formula, etc.) Thanks for the inspiration.
Hey, Joe! I haven't done a subtraction version yet, I'd love to see what you come up with.
