Inverse functions discovery— here’s a simple, hands-on idea for introducing inverse functions. It can also be used to discover geometric transformations over y = x. All you need is a square coordinate grid, a hole punch and a pencil or pen. Recording all class data on the whiteboard as a class may be fun to do, too. Students will start to see that x and y swap spots in inverses. The hole punch I’m using here is 1/8th-inch with a 2-inch reach. #inversefunctions #geometrictransformations #teaching

And it wasn’t even made for spins 😬 This is the power pod. Its original function was for load positioning, you put it under your heels and work on getting into a forward load But I’ve been using it for spins for a long time and it’s one of my favorite tools! The larger size and slightly heavier weight makes you really have to use your wrist and fingers quickly and correctly in order to get the right spin The goal is to practice your spins and not see any wobbling or toppling when you throw the
