Nets and Surface Area

HOMEWORK

1. On a separate sheet of paper. Copy the images to the right (Please don't print and cut out. We would like you to draw them.)

2. Cut out each image and fold along the lines to make a 3d shape.

3. If you know the name of the shape, please name it on a separate sheet of paper. If not, just describe what the shape looks like. Save your 3d shapes to bring to class.

4. Based on what you learned from making the shapes. Do your best to complete Go Math pg. 417.
