Above all other things taught at the middle school level the most important is how to block and tackle another player CORRECTLY. It would be a HUGE benefit, to high schools, for the middle schools to run the same "bread and butter" plays and formations (while using the same terminology for blocking assignments and plays)as the high school teams. This should not limit the middle school coaches from putting in theier own plays. Defensively, a middle school team may not be able to run the same scheme as the high school team. But ALL football players need to know how to block and tackle.
How do high school spread offense teams coordinate with their middle schools? Do the middle schools try and run the same scheme?
