So excited about a lesson that I road-tested with my daughter and neighbor today. It's a twist on an old favorite. I'm thinking of this for 3rd grade. Instead of printing the same image they will modify the plate each time, adding a snowflake.
Could extend the lesson an additional week by collaging curtains or painting the back of a head as a silhouette (or just for early finishers). The three week lesson with my symmetry worksheet and step by step visuals are available here.
