Children quite often build symmetrically, but it's exciting to both them and me when they recognize it. I've been hearing a lot of, "Mrs. C.! Mrs. C.! This is symmetrical! Take a picture!" Many of the kids have "got" the concept when it comes to this context. Using the SMARTboard, we explored different lines of symmetry as well as multiple lines of symmetry. This creates a kaleidoscope effect. One link (it's on our "Links for Fun and Learning" page - check it out!) created a great deal of excitement. The kids were creating beautiful designs using the 'Symmetry Artist'. I allowed each person who made one to print ONE out each day. I was hoping to make a book, but I couldn't get anyone to part with their creation! I should have taken photos. I finally did get the camera out for the three pictured below. The one on the left shows multiple lines of symmetry and Ethan used the 'line' feature to distribute his name symmetrically around the edge of the design. The one in the middle is Nolan's. He had one line of symmetry and carefully drew the left side of the bat while the computer generated the right side symmetrically. I thought that was pretty amazing, since kids this age have difficulty cutting a symmetrical shape on a folded piece of paper and visualizing the half that they can't see, let alone doing it virtually. The one on the right is representative of the many intricate designs that were created!
