LITTLETON, Colo. -- This week’s 7Everyday Hero is using music to help kids learn. Volunteer David Greer sings while keyboarding. He said it works wonders at Jefferson County's Coronado Elementary School.

David teaches the kids Power Point and keyboarding on Excel in the computer lab and the kids are catching on. He volunteers every school day, and afterschool he gives guitar lessons. There's no mistaking his popularity.

David does all of this because of the kids, which is his reward for volunteering for the past six years.
