Building with Blocks and Marbles: In this class, we make stuff with marbles and building blocks. Then it falls down in weird ways. We’ll make mazes, we’ll play store, we’ll solve stories where the princess has to rescue the prince, we’ll make strange falling domino puzzles, we’ll make catapults. We use 3,200 classic wooden building blocks, the kind that Frank Lloyd Wright and Robert Oppenheimer played with, that helped make them so smart; and Cuboro, an ingenious Swiss-made marble run system that fascinates children and gets them thinking logically and spatially.
