This afternoon it was beautiful out and I was in such a good mood that I let my kids have "math centers"- which is code for free play since they're not allowed to have free play- for the last half hour.
During this time I could have been working one on one with some of my students, or getting some testing done, or organizing their writing folders. What did I do? I had one of my kindergartners teach me the cup song from Pitch Perfect.
