Knucklebones, provides cross-curricular presentations using, amongst other items, tennis balls. It is through these presentations that we leave behind over 25,000 tennis balls a year that can then be used by teachers to teach Art, Language Arts, Math, Music, Science, Social Studies Etc.

We accept donations of tennis balls from tennis clubs and athletic clubs throughout New England.  To provide us with a donation please email us at -

We'd like to give a big shout out to those clubs that have provided substantial donations to us: Cedardale Health and Fitness, Mount Auburn Tennis Club, and the Waltham Athletic Club.

We’re looking forward to working with you...

Knucklebones is always happy to speak with you about any questions or programming needs. Reach us today!
