The Boys and Girls Club of Chaffee County in Colorado shares about how they are using Khan Academy at the computer and integrated into physical activities in this video. 

In their own words:

Our club, a non-profit 501-C-3 organization with a charter from the Boys and Girls Clubs of America, provided a math skills program to children, grades 5-7, last year which had as it main, but not exclusive focus, the Khan Academy website. The children were enthusiastic and the volunteer coaches who worked with the children thought if was successful both in motivating and increasing the participants skills.

As a result of the local school districts decision to move to a 4-day week, our Club expanded its hours of service to include Friday mornings so that children would have a safe and constructive place to spend time, especially for families whose parents work on Fridays.
