Even with my own kids when they were in school and home for the summer it was always a one hour Disney or similar type movie put on with everyone watching and if they balked they were told to close their eyes and sleep then. Point is it wasn't optional to be in one spot for the whole hours basically doing nothing for them either since their bodies needed a break and they needed a break from each other. I had the hour to do what I wanted knowing exactly where everyone was. Then IF they had given me a chance to get done what I needed to do - ie not have to stop and constantly be on their case, we would then play a board game or something only the big kids could do. Anyone up to and including kindergarten had to rest but over that they were allowed up. Sometimes I would put their mats in the tv room and they had to rest for half an hour and then I would put the tv on if they had rested. That way I got nearly the full two hours.
