I think this would be a really useful tool. I often suggest that teachers incorporate more movement into the day and many don't know how to do so, afraid that they wouldn't be able to calm the children down afterwards. I would advocate for a tool such as you're developing and also that teachers incorporate movement throughout the day by having activities such as large block building, easel painting on large paper, children pushing in chairs, etc. that incorporates movement and 'heavy work' at all times, as well as transition times. A purposeful movement tool could help children and teachers a lot. Keep us posted!
