###### Vocabulary:

3D, Net, Face, Prism, Pyramid, Cube

Activities:

- Created geometric nets of 3D figures, i.e., rectangular prisms, cubes, and pyramids, by identifying the number of each shape, or face, and piecing them together.
- Accurately named each of their nets and measured the side lengths of the different faces.

###### Vocabulary:

Surface Area, Net, Square Units

Activities:

- Discussed vocabulary terms, namely "surface area" and how it relates to 3D figures.
- In tandem with the previous activity, students used their measurements to find the total surface area of their nets (limited to cubes and rectangular prisms) using a combination of addition and multiplication.

### Home Exploration

Find a few small boxes, preferrably with nice, sharp corners and edges. Tissue, cereal, and granola bar boxes work well. Using a ruler, measure out the dimensions of each of its sides/faces (front/back, left/right, top/bottom). Calculate the total surface area of each box.

Have paper handy so that the measurements can be written down or, if it's okay, use a permanent marker to label the dimensions directly onto the box.

Choose apporpirate units (centimeters or inches) so that the measurements are numbers your child is comfortable with.

Make sure all answers are labeled with proper units!
