Geo Activity

Sometimes I feel like I'm barely hanging on with my Geometry kids. Proofs about killed us (don't tell them there are more to come) and tackling circumcenter, orthocenter (which I didn't actually understand enough so we skipped it - a decision made in the middle of the lesson), incenter and centroid has also been difficult. But I came up with a "fun" idea for demonstrating centroid (center of gravity of a triangle). It might be the only one all year :)
