This interactive applet affords students the opportunity to work systematically in making and testing hypotheses. Learners receive points by choosing 13 spots on a 5x5 grid. They must figure out the scoring system in order to maximize their scores. Ideas for implementation, extension and support are included along with a printable sheet of grids.
