Ok, just having a little fun with the blog title. We have been working with polygons (many-sided figures). When we work with polygons, we learn about flips, slides, and reflections. Reflections brings us to Symmetry. When we look to see if something is symmetrical, there has to be at least one line of symmetry. Things must be exactly the same on both sides of that line. Some figures can have more than one line of symmetry!
They are Symmetrical Experts now! See how many things around you house have a Line of Symmetry!
