Welcome to learning in limestone our goal success for all Welcome to J.G. Simcoe Four shapes to choose from, so it’s a cube, I’ll remind you a cube, octagonal prism, octagonal prism Square based pyramid or triangle base pyramid. Basically, we are counting the edges and the vertices. So when you’re counting never remember to count at the top all the edges, then count the middle going down Mary and then count the ones at the bottom. So with the octagon we know there’s going to be eight at the top, eight down the middle, and eight up the bottom. I’m making a cube. The base tells the name. Square base, (pause), prism (off camera) No, pyramid. (Teacher asks) Why? Why is it a pyramid? (Student responds) Because it comes to a vertex. Yeah, so all of these edges meet at a vertex at the top so that makes this shape a square base pyramid. I went to this, then I counted, and put them all together. Yea!!! (hands clapping) (Class of students) Goodbye (waving)
