Riprap Friends strives to enable children with cancer to participate in any of the normal childhood activities they miss, as well as any new activities they are interested in pursuing while on treatment. Examples of these activities include creative, educational, and/or socially enriching pursuits, such as dance, visual art, knitting, photography, music, yoga, cooking, and martial arts. They may also include academic and vocational lessons, such as exercises in foreign languages, computer science, reading, mathematics, and educational games.
