As part of the Desmos Fellow's weekly challenge, I made the following to celebrate the Christmas season. When I shared it with my students, I told them that I created the graph and many wanted to know how the stars were "blinking". Designing activities and lessons to make students wonder why something makes sense or how something works is what I strive to do on a daily basis. I look forward to continuing to reflect and blog on January 2. Now for a much needed break!
