Blindfolded

Last week myself and Calvin’s teacher were impressed he could do the binomial cube blindfolded. Apparently this week he mastered the trinomial cube blindfolded as well. I didn’t believe his teacher...doing the trinomial with sight is difficult. So she sent me a video. 

Apparently he takes the blocks out and sorts them by color before being blindfolded and doing the puzzle. He uses his visual memory to find the right pieces and put them in. I asked if that was cheating, at least a little. Her response was that she teaches the kids to organize the blocks but no kid has ever done it before. So Calvin actually listened and followed directions. Apparently it is all the rage to do the trinomial blindfolded, except C is the only one who is successful at it.
