D - Round Robin Tournament
A great thing to do is to have a tournament or small tournaments go on during practice all season. Divide the team into smaller teams and play SAG or full ice games. Modify rules so that certain individual or team play skills are the focus.
This adds intensity and fun to practice.
Put up a chart and circle the winning teams. If there is a tie circle both teams. You can have a trophy or some other kind of celebration that they play for to add excitement.
