Geometry

Lyndhurst High School, Lyndhurst Public Schools

Course Overview

Geometry develops students’ understanding of spatial relationships, logical reasoning, measurement, and mathematical proof. The course emphasizes conceptual understanding through visual models, guided practice, and scaffolded problem-solving activities.

Instruction is differentiated to support students with varied learning needs. Lessons connect geometric concepts with diagrams, real-world situations, and previously learned algebraic skills while helping students communicate their mathematical reasoning clearly.

Topics Covered

  • Points, Lines, Planes, and Segments
  • Angle Relationships and Measurement
  • Logical Reasoning and Two-Column Proofs
  • Parallel and Perpendicular Lines
  • Congruent Triangles
  • Transformations and Symmetry
  • Similarity and Proportional Reasoning
  • Right Triangles and Trigonometry
  • Circles
  • Area, Surface Area, and Volume

Instructional Approach

The course uses visual representations, structured notes, guided examples, and repeated opportunities for practice. Complex concepts are divided into manageable steps, with multiple solution strategies used to help students build confidence and mathematical independence.

Formative checks, collaborative problem-solving, and individualized support are incorporated throughout the course to help students make progress toward both course standards and their individual learning goals.
