Students develop general descriptions for prisms, pyramids, cones, cylinders, and spheres as they investigate a set of three-dimensional shapes. Two-dimensional shapes are sorted in a variety of ways. A general description for polygons is developed. Quadrilaterals and parallelograms are analyzed and described. Lines, angles, and parts of circles are introduced. Transformations are analyzed, and position and location on grids and maps are investigated. A Bright Idea Geometry Journal is kept throughout the lessons.
