' It centers on an unusual idea about odd and even numbers that one of my students proposed. 2 The crux of the story, however, is the response I've received whenever I 've shown a segment of videotape from that particular lesson to groups of educators. First, wha t h a p p e n e d in the class: One day, as we began class, SPan announced, seemingly out of the blue, that he had been thinking that six could be both odd a n d even because it was made of "three twos."
