Julianne Moore has a loving new way to help struggling kids in America: send a valentine.

Just before Christmas, the 47-year-old actress read to elementary school students and met with parents in White Oak, Tenn., on behalf of Save the Children. The organization aims to improve children's quality of life through literacy, physical activity and nutrition programs.

Afterward, Moore, a mother of two, was inspired to offer Valentine's Day cards online in return for donations to Save the Children. The cards, featuring children's artwork, can be printed or e-mailed, and are available through Feb. 14 on the charity's Web site.
