THE WORLD OF POLYGONS
Students survey the slide show on Polygons and line symmetry. they create larger polygons with the shapes on a sheet of paper and trace the object on the paper and draw the appropriate lines of symmetry.

New Review Real-World Area Problems
Not all structures take the shape of a polygon. The 21st lesson in a series of 29 shows young mathematicians they can create polygons out of composite shapes. Once they deconstruct the structures, they find the area of the composite figure.
