very nice job of explaining inflection points and concavity! i like the use of color and i like that you use my silly words like 'frowny' and 'smiley.' the only vocab i would caution you on is the use of the term "slope" when talking about a curve that is not a straight line, since slope is used to talk about a 'constant' rate of change of straight lines. when talking about a curve, i would use term rate of change. other than that, great job!
Stuart, thanks for giving a great class. You have nice chart and simple explanations. Students will enjoy it!
