The Discovering Geometry approach improves learning in many ways:

  • The developmental focus of Discovering Geometry will help you meet your students where they are and guide them all to a high level of understanding. You'll find many opportunities both to support students whose progress is slower and to challenge more advanced students.
  • Discovering Geometry will help you bolster your students' understanding and retention of theorems, definitions, and properties as they perform constructions, measure figures, relate patterns and properties, and discuss their findings.
  • Algebra Review exercises—integrated when applicable to the geometry being taught—will make it easy to reinforce your students' skills and keep them on track for continued learning.
  • You will build your students' reasoning and proof skills by using the exercises and group activities in the new Developing Proof strand.
  • Investigations, visual representations, and opportunities for discussion will enable you to integrate multiple teaching modes into your classroom so that visual, auditory, and kinesthetic learners all benefit.
  • The real-world applications, puzzles, and extensions in Discovering Geometry will help you motivate students and keep them thinking.
  • The book's focus on critical problem-solving skills will help you cultivate a classroom of self-motivated, independent thinkers. Author Michael Serra's extensive classroom experience helped him shape a new approach to teaching geometry. Now in its fourth edition, Discovering Geometry has proven effective in countless classrooms across the country.
