General descriptions of quadrilaterals are developed and two-dimensional shapes are subdivided to form new shapes. Students classify triangles according to their properties and develop definitions for each type of triangle. Students explore points, lines, line segments, rays, and angles. Students identify and build three-dimensional shapes from given two dimensional representations. Students demonstrate proficiency with translations, reflections, and rotations. Students find the distance between points along horizontal and vertical lines of a coordinate grid. A Bright Idea Geometry Journal is kept throughout the lessons.
