GEOMETRY

Starting on MONDAY, we will be exploring geometry...



Grade 7 you will explore at least 5 of these 3D shapes (pyramids, prisms)





Grade 8 you will explore these 3D shapes (5 platonic solids)




When talking about 3D shapes, you classify based on edges, faces and vertices.

So as you create them, write down in a chart in your math tool kits books, noting each shape’s name, number of sides, faces and vertices.

Grade 7

Types of triangles. Recreate using toothpicks on a poster. HAND IN



Grade 8

Create 2-3 of the Platonic Solids



Construct AT LEAST THREE of the five Platonic solids [i.e., tetrahedron, cube, octahedron, dodecahedron, icosahedron], and compare the sum of the numbers of faces and vertices to the number of edges for each solid ON A POSTER.*hand in

FACES
VERTICES
EDGES


THEN ADD THE FACES PLUS VERTICES
COMPARE THAT TO THE NUMBER OF EDGES
WHAT DO YOU FIND?
