Let’s ReviewLet’s Review
A three-dimensional figure has a length, a width, and a height.
Let’s ReviewCore Lesson
A net is a two-dimensional pattern of a three-dimensional figure, that can be
folded to form the figure.
Let’s ReviewCore Lesson
Identify the net that we could fold in order to create this 3D figure.

In this lesson you have learned how to represent three-
dimensional figures with nets, by analyzing their faces and
bases.
Let’s ReviewGuided PracticeDraw a net for this rectangular prism.
Faces?• 6 faces• 4 rectangles• 2 squares
Let’s ReviewExtension Activities
Kennedy’s teacher asked her to draw the net of a rectangular prism. She drew the image, below. Explain to Kennedy what she did incorrectly.
Let’s ReviewExtension Activities
A dodecahedron is a 3D solid with 12 flat faces. Can you draw the net for this dodecahedron?
Let’s ReviewQuick Quiz
Draw a net for a cube.
Draw a net for this square pyramid.
