This engaging, creative unit has been endorsed by mathematics educators nationwide for its application of guided-discovery methods through cooperative, interdisciplinary activities. The story leads to free exploration of buttons, then sorting and classifying and a game of Guess the Sort.
Students design their own buttons and use a graphing grid to organize data.
Masters for these games and one supplemental activity are included. As in all GEMS guides, resources and literature connections are provided to help the teacher stock and expand the unit. Comment on this GEMS unit.
