Children spend 6 and a half hours a day on average in front of a screen.
The mass availibility of smartphone and tablets mean that children are spending far more time than ever staring at a screen. The one time of day that they cannot is during school, especially in playgrounds.
If we can take advantage of this time that children have to be outside and re-engage them into being active and looking away from screens, then it might trancend into thier life after school.
