Recently, I visited a classroom where they were working on a patterning lesson. They told me, "I am making repeating patterns and patterns by 2s, and 5s."  Students were excitedly choosing various items to show their patterns.  I asked students, "What are you learning?"  They replied with, "Patterns are everywhere."  When asked what was fun about it a few answers were "It's so fun I can't expain.  I feel like I'm learning and playing.  It makes want to do more."
