Michael Serra's Discovering Geometry will energize your geometry classroom, involving your students and making them active participants in their own learning. Students explore geometric relationships with a wide variety of tools, including compasses, computers, and graphing calculators. Instead of just memorizing rules and definitions, students perform constructions, measure figures, observe patterns, discuss their findings, write their own definitions, and formulate their own geometric conjectures.Filled with appealing graphics and lively writing, Discovering Geometry draws students in -- and the real-world examples and applications from many cultures and disciplines keep them involved and thinking. In addition, the book's focus on critical problem-solving skills helps students become self-motivated, independent thinkers. Teachers using Discovering Geometry see their classrooms transformed into exciting forums filled with energized problem solvers.This third edition is packed with even more powerful benefits than its groundbreaking predecessors:More coverage of algebra and coordinate geometry.Increased integration of technology.Gradual introduction of proof.A greater variety of investigative tools.Extensions to lessons.Assessment suggestions.New projects and exercises.An expanded teaching package.
