MG-A: Apply geometric concepts in modeling situations
Standards:
Technology-enhanced investigations:
MIT BLOSSOMS: Video lessons with additional teacher and learner resources. Descriptions are from the video summaries.
National Math and Science Initiative: Lesson: Using Linear Equations to Define Geometric Solids: Use this lesson for geometry within a unit on volume applications. Students write the equations of lines and graph linear equations that define bounded regions, calculate the areas and perimeters of the regions, revolve the planar regions about horizontal and vertical lines to create solids, and calculate the volumes of the resulting solids; they use technology (virtual manipulatives) to create and revolve planar figures about horizontal and vertical lines and model the conceptual understanding using a real world situation. Targeted standards include GMD-A.3, GMD-B.4, GPE-B.7 and MG-A.1. Common Core Math Practice standards 1-7 are also addressed.
NCTM Illuminations: Geometric Solids: Use this virtual manipulative to "learn about various geometric solids and their properties. You can manipulate and color each shape to explore the number of faces, edges, and vertices." View the solid or its net. You can also use this tool to help determine the relationship between the number faces, vertices, and edges.
