What are the properties of the following 3-d figure? • 6 faces, 12 edges, 8 vertices • 6 faces, 10 edges, 8 vertices • 8 faces, 12 edges, 6 vertices • 8 faces, 8 edges, 8 vertices 3a, 3b Day 1 (DOK 2)
Practice Faces: Faces: Faces: Edges: Edges: Edges: Vertices: Vertices: Vertices: Name the number of faces, edges, and vertices for questions 3-11 on page 412 in the text book.
Work It • Find the faces, vertices, and edges for the provided shapes. • You may use the actual shapes that Ms. Lonsdale has in the back of the room if you need help identifying these properties. • By the end of class, discuss with your group…. • What seems to be the relationship between the faces/vertices and the edges of any 3D shape? • If you complete this early, read pages 410-411 and write the definitions for each highlighted vocabulary word.
Exit Ticket 2.) What are the properties of the following shape? ____ faces ____ edges ____ vertices 3a, 3b Day 1 (DOK 2)
