This project takes a long time and is very challenging. The best thing about it is that it gives kids experience in working through those challenges. Students also leave knowing how to efficiently use a hammer (after hundreds of nails and a few sore fingers); how to divide decimals; and how to measure irregular shapes and curves. I also like how it many of the designs force your brain to see lines which are not there: its one more way for students to notice that what their brain senses is only an approximation of what is really there tailor made to their needs; it is not neccesarily a tool for accurate description.
