Description Orange Classes are designed to teach students the strokes and strategies of tennis on a modified court. Classes are for children ages 8-10 and are played with an orange ball that is 50% slower than regular tennis balls. These tennis balls bounce lower and are easier to hit, allowing kids to learn faster and have more fun! A 23-25 inch racquet is recommended.
