These geometric solids will enable my students to visualize geometric solids, explore the relationship between the 2D net representations and the 3D models, and find relationships between area and volume. Using the large geometric solids, students can see the types of solids learned about in class (prisms, pyramids, cones, cylinders, and spheres). They can make educated guesses about the volumes of prisms and pyramids with the same base shape and height, and then fill the solids with sand or a colored liquid to test their educated guesses. In small groups of 3 or 4, the students can work together in building the nets to create 3-D solids (with or without the help of the included solids), then this can be extended to creating nets from given solids. This activity helps in students' spacial skills and their ability to break down more complex shapes into simpler shapes. Knowing the simple shapes (like triangles and rectangles) that make up the 3-D solids can help students to find the surface area and volume of the solids and to discover the formulas on their own. My students will be able to work in small groups and discuss their findings, and the whiteboards will allow them to give instant feedback from their group explorations. Also, the whiteboards will allow me to get formative feedback on students' understanding of graphing (functions and conics). The whiteboards can also be used in the study of coordinate geometry, and students can plot points and find area and perimeter of 2-D shapes using the coordinate grids. All of these materials will help my students to get instant feedback, collaborate with their peers, and explore 2-D and 3-D shapes in a more hands-on way.
