ThrowBack Thursdays Review. On Thursdays I would project three problems from the past on the screen or whiteboard. It was not only a wake up call, but became fun as I embellished the slides with items from the past (see Preview). The "math past" was anything relevant from Algebra, Geometry, PreCalc or Trig and, of course, Calc 1. I designed many of the questions based upon something that was coming up. Love it!! 108 questions plus full solutions!! 36 Thursdays. Calc AB coming soon!
