Unity's kids classes use a cycling curriculum in 6 parts over three stages. During each stage all students are only required to master the curriculum for that stage. This allows children to make steady progress on the principles and concepts that lead to a mastery of the martial arts before they are developmentally ready to hold all of the curriculum cumulatively. The three stages that they progress through (Fireflies and Grasshoppers, Tigers and Cranes, and Monkeys) represent the growing developmental levels so that they are given just as much as they can master as they become capable of it. Once they reach Blue Belt at the end of the Monkey's cycles, they transition gradually to our cumulative curriculum since they are physically, mentally, and developmentally ready for it!
