So, we held our little costume contest. There were 31 entries(!) and all 2012 participants are pictured below. Based on discussion at the #globalmath costume party, I learned we’ve been doing this since 2009. History: 2011, 2010, 2009

First Place

@jreulbach  as @mgolding .

Julie receives a hanging organizer from the Container Store. These babies were all the rage at Twitter Math Camp this summer. I love mine because I hang it near the door and fill it with handouts. “Did I miss anything?” is a question I refuse to answer. I just point at the organizer.

Second Place


@j_lanier  as @natbanting 


@mrpicc112  as @approx_normal

Justin and Timon will have to fight it out over graph paper composition books and Command Strip adhesive poster strips.

Several math teachers swear by the graph paper comp books for their Interactive Notebooks, saying it helps kids organize their problem solving (not to mention, it provides a handy Cartesian plane all the time).

The poster hangers are about the only method I know to hang posters in a room with cinderblock construction. Colleagues of mine swear by the glue gun but regret it in May when taking things down. These suckers work.
