The explorations are not easy, but they offer a great opportunity for students to step outside of their math comfort zone and grow as mathematical thinkers. [ They] would provide upper middle school students with creative, and differentiated, problems to solve, as well as provide a review of learned concepts.,Kathleen Palmieri,MiddleWeb,10/11/18 Overall, I believe this is an excellent resource for any teacher in the middle or upper grades who is looking for support in implementing cognitively demanding probability and statistics activities in their classrooms. Many of the problems within each exploration can be used as stand-alone tasks or as part of the intended exploration as a tool for developing deep conceptual understanding.,Michelle Morgan,University of Northern Colorado, 10/15/18
