his math assignment is half geometry and half art. An appropriate lesson for geometry, algebra or pre-algebra. It is a proof of the Pythagorean Theorem without numbers. Students start with a large paper square and add lines, labels, and folds on it to make the proof. You may find different versions of this lesson on the net. But it is unlikely you will find anything which puts the math and visual examples together the way I do. It is much easier to understand the proof this way.
