Geometric Investigations on the Voyage 200 with Cabri...The emphasis of the 11 activities in this book is on student exploration and the discovery of geometry principles through plausible reasoning. Any exploration can be used where it fits into the math classroom. The explorations in this book are intended to promote an environment of inquiry through thought provoking, open-ended problems. There is no intended order of topics. Any exploration can be used where it fits into your program. There is no suggested time for an exploration. Some students may think about a given problem for weeks or months, coming up with new insights and interconnections as they consider other problems. It may be appropriate to present one exploration, or part of one, each grading period as a group or individual project.
