Problem 1. Review: Cone, Cylinder, Sphere.
Discuss: Rectangular prism, Cube, Pyramid.
Problem 2. Look at the “bags” with the shapes. What do you notice? Draw in the missing

Problem 5. Find the missing parts of these prisms.
Problem 6.

Problem 7. Look at the cone. Does it remind you of a wizard’s hat? What do you think?
Where does the cone have a point (apex)? The bottom of the cone is called the base. It has
a circular flat base and curved side that ends in an apex point. If we look at the cone from
the top, we can see a circle with a point in the center. Why do you think it’s like that?
What shape has a pyramid base? (Square). Also the pyramid has sides. The 4 Side Faces
are triangles which meet at the top (the apex). It has 5 Vertices (corner points). It has 8
Edges. A cylinder has two identical flat ends (base) that are circular or elliptical and one
curved side.
How do these shapes look like from the red pencil point of view? What are their
projections (photo)?
Connect each shape with the correct projection.
Torus - a round 3-D shape with a hole in the middle, like a tube or a doughnut.
