Keeping your materials neat, organized and in order helps them last longer and makes game time more efficient. These tips are based on how the materials are most often used in the games.
Why take the time to sort the rhythm playing cards into notes and rests only to pudding shuffle them before the next game. Set an example by teaching your students/children to help you clean up your materials after each game rather than by yourself at the end of class.
Soon they will know how to clean up on their own, giving you time to prepare for the next game or make notes of what games you played. As they see you taking care of your materials, they will do the same and your materials will last a long time. There are also many games created for cleanup.
