Give your students a good understanding of geometric planes, lines, points and dimensions with geometry textbooks and activities. Typically taught in the ninth or tenth grade, geometry is the study of shapes and their properties. Geometry workbooks and activities will help guide students in both traditional and home school classrooms through the concepts and theories of geometry and form a solid foundation for advanced learning in mathematics. Using foam, wood or plastic models, children will easily learn to grasp plane and solid geometry, congruents and similars, polygons, quadrilaterals and much more. Instill in your classroom an appreciation for higher math and its concepts with geometry textbooks and geometry activities.
