The linear transformations unit in my textbook starts by discussing functions on the first day, followed by reflections, translations, rotations, and dilations. I go quickly through these topics one day at a time and then return to them, starting with reflections on the second pass.
On the first pass I use the WebQuest to supplement each linear transformation type: For example, on day 2 we discuss reflections as defined in the textbook; that evening the students visit the WebQuest for the topics that deal with reflections.
On the second pass, the students work on the creative thinking project of the WebQuest.
