Do you know Go Noodle? Its a brain break interactive site that gives students and teachers 3 min breaks by incorporating exercise, dance, and even songs into short brain breaks. My class is hooked on this and ask for Go Noodle all the time. I love for the exercise breaks, there are real cameos from Olympic athletes. The brain breaks are well designed and are broken down from energizing to calming.
If you haven't already come across it yet, check it out
