Be sure to have students who used different nets for the same rectangular prism present. Then have students give their presentations. They are all nets of cubes except for net d and net e.Īsk students to share the strategies they used to decide whether a figure is a net for a cube.If the squares overlap, will the net form a cube? How do you know?.Student has difficulty identifying which patterns are nets for cubes. If they build each prism using a net drawn on a sheet of paper, they will be able to easily turn it to look at the faces. If cubes are available, some students may choose to use them to build the prisms. To identify which nets form cubes, some students may want to copy the patterns onto grid paper, cut them out, and fold them. Mathematical Practices 5: Use appropriate tools strategically. Some students may need to build each cube from the given nets to make a conclusion. Provide graph paper with large squares and tape to assist students in physically building the prisms. Provide physical manipulatives to support students' understanding between the net and a prism. Students who are having trouble identifying the nets of cubes may wish to copy the nets onto grid paper, cut them out, and fold them. Have students work solo to start and then move into partner work after a few minutes. Then they will sketch nets to determine the surface area of rectangular prisms. Tell students that they are going to look at different arrangements of squares and decide which arrangements are nets of cubes and which are not.
