Yes, that’s on our resources page for Math – I’ve spoken with Dr. Benjamin and he’s such a blast!

Aces! After showing this video to my daughter she decided she wanted to do a “Magic Math” presentation to her class! Then the wheels started turning and she wanted to see if the same method would work for 3 numbers! Love to see her THINKING and PROBLEM SOLVING!
