In these lessons, you'll learn about some of them. You'll learn some of the terminology used to describe them, how to calculate their surface area and volume...Subjects: math, geometry, surface area, volume, test, skills, shapes Geometry Through Artby Norman Shapiro Ages: 8+To children, beauty comes before logic and theories; therefore, geometry as art seems the most natural approach for teaching this subject.Subjects: math, El Greco, shapes, proportions, logic, theories Virtual Geometry Manipulativesby Utah State University Ages: 4 - 18Learning and understanding mathematics, at every level, requires student engagement. Mathematics is not, as has been said, a spectator sport. Too much of current instruction fails to actively involve students.Subjects: math, geometry, lessons, kids, downloads, library  The Geometry Junkyardby David Eppstein Ages: 12+I've heard parents complain "my daughter makes collages from magazine clippings in her high school geometry class instead of learning real math". Some of the lesson plans listed here are like that, but are perhaps appropriate as auxiliary material.Subjects: math, geometry, lesson plans, coursework, teaching materials Perimeter and Area of Polygonsby Math Goodies Ages: 10 - 17Perimeter & area of polygons are introduced in this unit. Perimeter of polygons and perimeter of regular polygons are covered. The difference between perimeter and area is explained. Choose from the table of contents below, or try one of our other topics.Subjects: math, geometry, perimeter, lessons, polygons, worksheets Geometry Lesson Plan Sites - Math Forumby Drexel University Ages: 12+This list contains some of the best geometry lesson plan sites.
