Joe Nichols took on a team of fifth-graders this past week on a special celebrity edition of the TV game show, 'Are You Smarter Than a 5th Grader.' The singer tackled subjects ranging from geography to social studies, and played for his favorite charity, Camp Barnabas in Missouri, which provides life-changing opportunities each summer for some 1,300 kids with special needs from ages 7 to 17.

Joe donated his winnings of $125,000 to the camp. Because of Joe's donation, Camp Barnabas will be able to break ground immediately on a much-needed health-care facility. His younger sister, Kelli, has been among Camp Barnabas' attendees over the past several years.

"Every camper who comes to our summer program has a medical need," says Cyndy Teas, the camp's co-founder and director of development. "Applying the money from Joe in this way provides the maximum benefit for the dollar to all of the campers. We are so appreciative of his honoring us and his sister Kelli in this way."

Joe has been on the road in support of his critically acclaimed album, 'Old Things New,' and will continue touring through early December. His current single, 'The Shape I'm In,' recently cracked the Top 30.
