I was concerned about the topic about students sitting at their desks for 7 hours per day. I’m a teacher and I look for ways for students to move around in my classroom as much as possible. We take exercise breaks, we make up movements to go with things we are learning, we move around the room in small groups, we have recess (of course), etc… I would hope that most all teachers out there know that making a child sit for 7 hours a day is ineffective and is not good for the body or the brain. I know that I couldn’t sit for very long and be expected to pay attention. A great book to read about the brain and the importance of exercise is Brain Rules by John Medina.
