Montessori math lesson reinforced at the St. Louis Science Center! Got to appreciate that!
From VdM Parent, Cab Yau:
I love this picture of Hank from our spring break in St. Louis. We were at the Science Center, and he ran to the display that said “math.” He loved these turn-an-x (hexagon, octagon, triangle, etc.) -into-a-square puzzles. I asked him if they were kind of like his equivalence plates. It was pretty cool because each one was broken into specific shapes that you had to make fit into the other shape, and it told of the person who found out about this particular equivalence – and some were fairly recent (1926!).
