Students explore a set of three-dimensional shapes to develop comparisons of polyhedra, cones, and cylinders. Students draw the front, top, and side views of a three-dimensional shape built with cubes and identify nets for a variety of polyhedra from drawings. Triangles and quadrilaterals are classified according to their properties. Transformations and tessellations are explored. Conjectures about the perimeter and area of regular two dimensional shapes are made and tested. Coordinate grids are explored for position and location. A Bright Idea Geometry Journal is kept throughout the lessons.
