### PI explained visually using a polygon

Thanks Matt
Perhaps you can add this resource

It explains PI by using a regular polygon, as the number of sides increases the polygon approximates to a circle. So if the polygon is opened you can measure its perimeter against a ruler with is equal to 2π

Some great resources here! Though that video is exactly the kind of thing that, had I watched it as a kid, would have convinced me that I was horrible at math. The explanations went way too fast and Max was way too capable of comprehending them on the first go-round. It seems that, sometimes, by presenting an idealized version of learning and glossing over the lengthy and challenging processes that it involves, we may be simply reinforcing the idea that some kids are capable and others are not. Possibly even making those who have to struggle a bit more than Max does in that video feel "stupid". Possibly.

We, in The Big-Brained Superheroes Club, are celebrating "March Mathness" this month. We're going to try to make it a yearly thing. Just to spread the Math word, if possible.
