There is no right or wrong way to organize learning centers, and you may want to alternate your center use throughout the year. The number of centers you have at one time may depend on the size of your room, the number of parent helpers in your classroom, and the curriculum. There is a plethora of ways you can schedule learning centers in your classroom. They may be used on specific "learning center" days or as a time when students can follow up on a lesson recently taught in the class. You may wish to have learning centers up and running at all times so that when students are done with their work, they can spend time in a center.
