I have been awaiting the day that we could add the binomial cube to our classroom. Finally I had the funds available to make a purchase that included the cube.
I brought it out to show Charger and gave him the demonstration. He looked at me, the cube and said. 'That's easy, Mom.'
So away he went...
Elapsed time? About 2 minutes. Let's hope that doing it blind folded will at least be a challenge.
And, I know I have 2 more students to try it in the future. Oh well, I really like it :).
