Name the following
3D shapes:
- Nets, Prisms, and Cylinders Approximately March 17th to May 2nd
This unit will help you develop an
understanding of 3D Shapes.
This will help you with everything from
painting your bedroom teal to making koolaid for your friends!
We will learn how to work with:
- 2D Patterns (Nets)
- Surface Area of 3D Shapes
- Volume of 3D Shapes
In your table groups create a list of the
products I would need to buy in order to
make cake for your teacher...
mmm cake!
(Switch sheets with another group)
Place a checkmark next to a product if it
matches the shape of the container it is
packaged in.
Brainstorm about what might influence a
package choice:

Dez has a box she is using to carry kittens
to school for everyone to play with.
How much volume is available to fill with
kittens?
In groups of 4:
Predict which box has the greatest volume,
no measurements or picking up boxes

If I filled a box with 1-cm cubes, what would
the area of the base represent?
What other dimensions do you need?
If I filled a box with 1-cm cubes, what would
the height represent?
How can you use the area of the base and
the height to find the volume?
What variables does the box have?
Does volume change if I flip the box over?
