Centroid Activity

[Sharma]

After explaining what the centroid is (the intersection of the medians), I pass out mini cardboard triangles for the students (They can share or pass around). If they can find the balancing point of the triangle, they’ve found the centroid. Even challenge them to use a smaller point, like the tip of a pencil, to find a more precise centroid.

Also, it’s worth explaining after they’ve tested out the cardboard triangle activity that a triangular table, though rare, really only needs one leg to stand. The leg would of course be at the centroid.
