Common Core High School Geometry Teaching and Learning Resources

MIT BLOSSOMS: Video lessons with additional teacher and learner resources.  Descriptions are from the video summaries.

• Building Cryptosystems: "This video module presents an introduction to cryptography – the method of sending messages in such a way that only the intended recipients can understand them. In this very interactive lesson, students will build three different devices for cryptography and will learn how to encrypt and decrytp messages."  Aligns with MG-A.3.
• Engineering Innovation and Entrepreneurship: "This video lesson introduces students to the worlds of engineering innovation and entrepreneurship. ... The video will familiarize students with all the steps in the innovation process: from conception to launch. By the end of this lesson, students will be prepared for an optional long-term innovation project."  Aligns with MG-A.3.
• Using Geometry to Design Simple Machines: "This video is meant to be a fun, hands-on session that gets students to think hard about how machines work. It teaches them the connection between the geometry that they study and the kinematics that engineers use -- explaining that kinematics is simply geometry in motion. In this lesson, geometry will be used in a way that students are not used to."  Aligns with MG-A.3.

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.
