Once students have created their nets, they may save or print them for assessment or use<br />
them <strong>to</strong> create figures.<br />
LEARNING CONNECTION 2<br />
Net Characters<br />
MATERIALS<br />
• 3D5.BLM5a–b: Net Characters (1 per student)<br />
• Polydron sets (1 set per group of 4 students)<br />
Arrange students in groups of four. Distribute 3D5.BLM5a–b: Net Characters <strong>to</strong> each student.<br />
Begin by asking students <strong>to</strong> predict whether the first character is a net for a prism, a pyramid,<br />
or another three-dimensional figure, <strong>and</strong> have them name the three-dimensional figure that can<br />
be formed by folding the net.<br />
Next, invite a student <strong>to</strong> come up <strong>to</strong> test the prediction with the Polydron shapes. Once the<br />
correct figure has been confirmed, instruct all students <strong>to</strong> record the name of the figure on<br />
their h<strong>and</strong>outs. (square-based prism).<br />
Students continue <strong>to</strong> identify the nets of pyramids <strong>and</strong> prisms from several character nets on<br />
the h<strong>and</strong>out. Allow enough time for each group of students <strong>to</strong> try <strong>to</strong> identify each net.<br />
Distribute Polydron sets <strong>to</strong> each group. Instruct groups <strong>to</strong> test their predictions for each net by<br />
constructing the net <strong>and</strong> folding it <strong>to</strong> create a three-dimensional figure.<br />

Complete the Nets<br />
MATERIALS<br />
• a partially completed net constructed from Polydron shapes, as shown<br />
• one additional pentagon <strong>and</strong> one additional square Polydron shape (hidden)<br />
• 3D5.BLM6a–b: Complete the Nets (1 per student)<br />
• rulers (1 per student)<br />
• Polydron pieces<br />
Begin by showing students the partially completed net constructed from Polydron shapes below.<br />
Tell students that the net is missing one or two faces that you have hidden. Ask them <strong>to</strong> predict<br />
what the three-dimensional figure is <strong>and</strong> <strong>to</strong> tell you what faces are missing. Ask: “How do you<br />
know?” (It is a net for a pentagonal prism with one pentagon <strong>and</strong> one square face missing.)<br />
