This activity helps students to understand nets and how they can be used to create three-dimensional figures.
Students will work with a partner to determine which arrangements of two-dimensional shapes are nets, and they will also redraw the arrangements that are not nets so that they become nets for rectangular or triangular prisms.
Questions
- What is a net?
- How can you determine if an arrangement of two-dimensional shapes is a net?
- What three-dimensional figures can be made from nets?
Answers
- A net is a two-dimensional arrangement of shapes that can be folded to create a three-dimensional figure.
- To determine if an arrangement of two-dimensional shapes is a net, you can try folding it to see if it makes a three-dimensional figure. You can also count the number of faces, edges, and vertices in the arrangement to see if it matches the number of faces, edges, and vertices in a three-dimensional figure.
- Nets can be used to create rectangular prisms, triangular prisms, and other three-dimensional figures.
