We finally discovered the Power Rule today in Calculus, and then used it to write tangent lines to polynomials and find derivatives of functions with rational exponents. I had the kids make up crazy polynomials to show how powerful the power rule is (pun unavoidable). I mentioned that there are an infinite number of functions they can already find the derivative for, which really pumped one kid up….

Little does he know that there are an infinite number of functions that they can’t find the derivative for!
