the Common Core State Standards for Mathematics, Discovering Geometry, Fifth Edition creates learning trajectories
that match the standards and the progression of the content from middle school
and into advanced mathematics. Click here for an overview of the Discovering Mathematics series and here to

Discovering Geometry accounts for the changes in the
CCSS content standards and aims to revisit them in various contexts that show
connections within the mathematics.
similarity, and symmetry are now studied from the perspective of geometric
transformation. Now introduced in
Chapter 1, congruence is defined through rigid transformations. Similarity is now defined through similarity
transformations (rigid motions followed by dilations).
Many of the
inductive elements (understand and explain standards) are now part of the
geometry strand for the middle grades.
High school geometry is now more focused on deductive proof and
application. The Developing Proof section of each lesson helps students connect
their inductive experience in the investigations with the deductive proof
required by the standards.
Analytic geometry has become more integrated into the high school geometry course that most districts and states have studied in the past. Coordinate Geometry lessons in each chapter help students make the connection between the synthetic geometry covered in each chapter and the analytic geometry required by CCSS.
Discovering Geometry embraces the principles of the Math Practice standards through its investigative approach that guides students to create conjectures through investigation and use
inductive and deductive reasoning to justify their response.
Author Michael Serra’s extensive classroom experience has helped him shape a successful
approach to teaching geometry. The program’s combination of research-based pedagogy and rigorous content will help you cultivate a classroom of self-motivated, independent thinkers who will succeed on today’s assessments and in advanced mathematics courses.
