COURSE DESCRIPTION Common Core Geometry begins with a review of geometric definitions, theorems and characteristics. The curriculum develops the concepts of triangle congruence and similarity by considering the transformation of figures in the coordinate plane. The curriculum includes topics such as transformations, congruence, proofs, constructions, similarity, right triangles, trigonometry, area, volume, geometric modeling, coordinate geometry, circles and parabolas. Incorporated throughout the lessons are video tutorials and interactive presentations. Lessons are designed using a best practice model that includes scaffolding, vocabulary, prior knowledge, guided practice, independent practice, and written response opportunities for students to solve, analyze, and evaluate concepts.
