Brain breaks can be great to use after transition times (ie. after recess), when your students are restless, or when students are struggling to pay attention. If you’re introducing these activities to your class for the first time, I’d recommend starting with activities that have limited movement, minimal physical contact and simple rules. Then, progressively increase these factors over time. I’m also a big believer in a quick game being a good game. Don’t play a game to death – call it quits while people are still enjoying it. This leaves them wanting more and means you can reuse brain breaks over the year (see if students can perform ‘better’ the second/third time round).
