Snowflake Collages

     I really love projects involving snowflakes because of the technical, mathematical aspect.  Now, I will admit the ONLY mathematical theories that I enjoy are those involving symmetry and shapes...that's it!  So, to introduce this lesson, we always begin with an overview of symmetry and rotational symmetry.  By this point in the year, 3rd-6th graders are pretty familiar with the concept of symmetry so I'm basically just reinforcing what they already know and giving them a hands-on approach to further stretch their knowledge on the subject.  I showed the class several different examples of snowflake designs that I found on the ever-handy Google Images.  Next, I passed out strips of paper that measure 6" long and 1/2" wide.  They are encouraged to start the snowflake by gluing strips of paper in an X and putting one or two more strips of paper through the middle of the X both horizontally and vertically.  Now the fun begins.  I show them how to cut the strips into little pieces to add details to their snowflakes.  I reinforce that each line has to be the SAME in order for the snowflake to remain SYMMETRICAL.  Here are a few great examples from 4th grade:
