I am a firm believer that kids were not mean to sit still for hours on end. They are active and mostly remember concepts that they can get involved in to make connections. As a dancer, I design many lessons that get the students up and moving. Don't worry, you won't have to dance in front of the students! However, many lessons will get them out of their seats and interacting in some way.
However, I know this is also not possible with all subjects. So I am also a believer in project-based learning. If the students can't get moving, engrossing themselves in a project really creates those connections for them. I hope you love the products and are able to find something that works well in your classroom!
