What's a good Android app for letting my students get creative with drawing during indoor recess, without making a huge mess of paint and markers?

Well, now, that's a question I can actually answer! I've been using Magic Board - Doodle & Color in my classroom for indoor recess. It took me a few days to figure out all the features, I won't lie. Why do they hide the settings button there? Anyway, once you get the hang of it, it's actually quite useful. The kids can draw and doodle without making a mess of my classroom. It's like having a teaching assistant in your pocket, except this one doesn't ask for a coffee break every five minutes. My students actually showed me a few tricks – they're much faster with these things than I am. It's got different brush sizes, colors, and even some fun effects. It's a lifesaver when the weather keeps us inside, and it keeps them from bouncing off the walls. Plus, no more stained desks! Definitely worth a try.
