3-D Shapes Cube Cylinder
Pyramid Rectangular Prism
Go on a scavenger hunt around the classroom to see if you can find the following: Cone Rectangular prism Pyramid Cube Sphere Cylinder
Shapes have …. Faces (or sides) Vertices (or corners) Edges (where sides come together)
Count the faces _____ Count the vertices _____ Count the edges _____

What if…. You combine a cube and a pyramid – what would you make ?
You combine a cone and a sphere – what would you make?
You combine a rectangular prism with a cylinder – what would you make?
Make your own new 3D object using at least 2 shapes. ?? ? plus

Shape up to Geometry There are six 3-D shapes we need to know * There are six 3-D shapes we need to know: cone, cube, cylinder, rectangular prism, pyramid, and sphere. A line of symmetry meansA line of symmetry means : both sides of a figure are the same size when a line is drawn down the middle. We can combine shapes to make new shapes * We can combine shapes to make new shapes.
