My 8 year old grandson lives in Leesburg and is a good swimmer. I don't worry about him when in the pool here in The Villages.
He took lessons at Venetian Gardens Swimming Pool in Leesburg. Here is the link to its summer swim program and phone number to call. Be sure you go to Page 3 to view the swimming information

Leesburg Parks and Recreation also offers football, soccer, and tennis lessons for the 11 year old age group.
Another idea is roller skating at Leesburg Skate World
Skate World, Tourist Attractions, Leesburg, FL 34748 - index. It's a good place for youngsters to meet others their age.
Horseback riding lessons:

Don't overlook church activities. Most have Vacation Bible School.
Good luck keeping this pre-adolescent busy. It won't be easy but it's not impossible.
