Week 1 Reflection: 3D Shapes

Over the last couple of days we have been working with 3D shapes. 3D stands for three dimensions and the three dimensions of a 3D shape are length, width and depth. The parts of a 3D shape are faces, edges and vertices (corners). The first pic below is a pyramid made out of sticks and glue tack. Pyramids have 5 faces, 8 edges and 5 vertices. The second pic is off a diamond. Diamonds have 8 faces, 12 edges and 6 vertices.
