LEGO Education has tallied the results of its survey about LEGO organization in class/club settings, and here are the results.
I want to hold off on my opinion for now. What do other teachers and coaches think? Be sure to look at the sidebar gallery.
I have a couple of weeks to figure out how to organize a big pile of LEGO pieces for a dozen different summer camps/classes. It won't work to store everything in the boxes in which they came. I'll post photos when I figure it out.
