My kids love go noodle - I feel like they get a break from the intensity of focused learning and we can kind of bond as well!

I agree that smoothies are great. There aren't many greens that I really enjoy, so having smoothies helps me get the nutrition I need. I also juice, which is somewhat controversial. Here's some info on that from web MD... https://www.webmd.com/diet/features/juicing-health-risks-and-benefits#1

Go Noodle (gonoodle.com) is a website that has a variety of activities that you can do with your students. It has activities there that would interest all ages. There are activities specifically just for elementary students. These are the supplementary videos for lessons in the class (Reading, Math, Science, Social Studies, Nutrition, etc). There are activities that are appropriate for middle school and high school students (behavior management, yoga, exercise, ice breakers). I sometimes use it as an ice breaker for trainings with our teachers. Sometimes, I use the exercise videos to wake my students up. You just have to decide if you feel that your students are the ones who wants to have fun and it will be a good fit for you and your class. :)

Glad they enjoy what they do during break. Kids love to do that sort of thing. Try Go Noodle as well. Even though it is more for the younger ones. They would like the movements.
