My Routine:
If there is a DM lesson for the week, I teach it on a Thursday (last day of the week for the class).
The next week, on the Monday & Tuesday, after the opening prayer, we play one of the 5-10 minute games. We focus on just the one DM we learnt on the Thursday.
On the Wednesday, after the opening prayer, we play one of the 5-10 minute games which uses all the DM we have learnt so far that year.
On the Thursday I start with the lesson. I finish the lesson 15 minutes before the end of class and we enjoy the end of the week by playing one of the longer DM games.
These are just ideas. Find what works for you and your class :)
