Symmetry on the Rectangular Coordinate System An Investigation
Ref-y
In grades 9-12 all students should
° use Cartesian coordinates and other coordinate systems, such as navigational, polar, or spherical systems, to analyze geometric situations; ° investigate conjectures and solve problems involving two- and three-dimensional objects represented with Cartesian coordinates. ° understand and represent translations, reflections, rotations, and dilations of objects in the plane by using sketches, coordinates, vectors, function notation, and matrices; ° use various representations to help understand the effects of simple transformations and their compositions. Prior to completion of Grade 12, students will: 3. Analyze advantages and disadvantages of widespread use and reliance on technology in the workplace and in society as a whole. (2) 8. Select and apply technology tools for research, information analysis, problem-solving, and decision-making in content learning. (4, 5) 9. Investigate and apply expert systems, intelligent agents, and simulations in real-world situations. (3, 5, 6) 10. Collaborate with peers, experts, and others to contribute to a content-related knowledge base by using technology to compile, synthesize, produce, and disseminate information, models, and other creative works. (4, 5, 6)
