Excel

I never realized how much you can do with excel. In high school we occasionally used excel for spreadsheets or graphs but i never really learned all the cool things you can do like plugging in equations and formulas. Excel is a great tool for math and stat classrooms, i wonder why our teachers never used them to the full extent that they could have. I guess most of my teachers were not aware of how useful it could be. It is a transition from boring mathematics to using a computer which most students enjoy doing.
