• These are the seven three dimensional shapes we are going to be learning about in this unit. Looking at these shapes and thinking back to our previous units on polygons, what can you figure out about how polygons and three-dimensional solids are related?

• Jot down initial ideas.

Bridge

• Now let’s see what else we can learn about three-dimensional solids including what makes each unique, where we can find them in the real world, and how we can draw three-dimensional figures only two dimensions.

Prisms

• Visual • Points to rectangular bases• Numbers faces with a marker• Think of real world examples• Close eyes and see shape clearly in their mind

and repeat its name• Show how to draw with dotted and solid lines

Question

• One of four learning styles• Cover your organizer . Without looking, which

critical attributes of triangular and rectangular prisms can you remember?

Pyramids

Question 2

• One of four learning styles• Compare and Contrast prisms and pyramids.

What are two similarities? What are two differences?

Cylinders, Cones and Spheres

Question 3

• One of four learning style• If you l had to wrap two presents, one shaped

like a cylinder and one shaped like a cone, which would harder to wrap? Why do you think so? Of all the shapes we’ve looked at so far which would be the easiest and which would be the hardest to wrap?

Question 4

• One of four learning styles• Which shape would you say is the ‘oddball’

among our family of three-dimensional solids? What makes your choice unique?

Synthesis Task

1. I want you to imagine that you’ve been asked to create an aesthetically pleasing monument dedicated specifically to three-dimensional solids. Your monument must use all seven solids we’ve learned about in this lecture, but you are free to use each solid more than once or to combine different solids to create more complex shapes. Create a sketch of your proposed monument and label each solid within your design.
