It's more about cultivating the child's sitting, standing, walking and other body coordination to work together. This time does not need the child to do too many difficult movements, more to develop the child's sense of beauty, as well as physical flexibility exercise. In the child 10 years old to 12 years old when you can begin to more formal practice dance, add a little flexibility greater movement.
Each age group has something to learn for itself. For example, children between the ages of 3 and 6 don't need very technical dance. This is because the child is in a developmental stage at this time. Early exposure to technical dance moves will only hurt the child's bones.
