22 slide bright and colorful powerpoint. Used during an observation and got innovating! Starts out with defining what a tessellation is with examples. Then covers the three regular polygons that tessellate with an explanation of why including pictures. This power point also cover irregular polygons that tessellate, as well as, M.C. Escher tessellations. It is minion themed and includes an exit slip and a list of tessellation websites for games. This really is the all inclusive tessellation set that I was looking for but couldn't find, so I made it myself! Reward the kids at the end of your lesson with pretzel rods and tell them they are radical (radical)!!!
