This fall, I'm going to start a new job as an after-school educator at a K-5 school. Part of my job involves planning an enrichment activity that I'll lead for an hour or so per day, all semester. I've been given a lot of leeway in my lesson planning, and right now I'm leaning heavily towards teaching theater arts, as improv activities are fun, cheap and cooperative. This is a younger group of students than I've ever worked with before, and I'd be grateful if anyone can point me towards books or other resources that might be helpful for my lesson planning, classroom management or both! Thanks for your help!
