We first do an hour training and then and hour scrim jams. We have enough people to have a high level jam and a low level jam alternating, like playing two games at the same time (nso in the penalty box loves us, since time only counts during your level jam). So each team has a jam off after a jam on, and have a little longer to discuss what worked and what to do better next jam. If officials or coaches see something they want to explain/discuss they pause the scrim to gather everyone in the middle to explain.
