Lilyana’s Adventures in the Third Dimension

Yesterday Lilyana came home from an trip to the Boston Museum of Science noting that everything she could see was three-dimensional, and wondering what one and two dimensions looked like. That led to lots of drawings of points, lines, and planes spread over the kitchen table, and extruding a salt shaker from a piece of paper. I’ll have to skim Flatland to see if that is good bedtime reading material!
