Start your high school Geometry course with the foundational vocabulary, notation, diagrams, and measurement skills students need before moving into proofs, angle relationships, triangles, and the rest of Geometry.

This Intro to Geometry Unit covers points, lines, planes, segments, rays, angles, segment addition, angle addition, midpoint, distance, basic postulates, and Geometry notation. Students practice naming figures correctly, reading diagrams, measuring with rulers and protractors, using segment and angle addition, and applying midpoint and distance on both number lines and coordinate grids.

This unit includes complete lessons with notes, practice pages, hands-on activities, editable assessments, digital options, task cards, and answer keys. It is designed to help students build confidence with the language and structure of Geometry while giving teachers ready-to-use materials for the beginning of the year.
