Because we’re now teaching IB PreCalculus and Calculus, we’ve moved our extra lab block down to the junior year. This means that the pre-calculus honors classes have started derivatives. If you teach derivatives, you need to do this before even mentioning the power rule. Each student gets a unique function that they need to find the derivative using the difference quotient and then post their result on the board. Their task is to find out the rule (but no helping others!). I let them burn on it overnight.
