Do girls build differently?
Here you can see a group of girls in their classroom building with big blocks and these funny blue things we have that have the hook side of Velcro on each end. The blocks represented a ship. there were 'bad guys' on the other side of the room. The blue things were water, then food and money (when they put them inside of a block). Did the points represent waves? It strikes me that within this group of girls, at least three (if not all five) of them have strength in spatial/mathematical thinking and interest in engineering -building, making gadgets and folded paper constructions.
