Chelsea Rae Chambers, 11, of Potsdam, N.Y., a sixth-grader at St. Mary’s School in Canton, raised money to buy school supplies for disadvantaged children by creating and selling the “Kids for Kids” cookbook, a collection of recipes donated by children in grades K-6. When Chelsea discovered that many families in her community had no money for back-to-school supplies, she wanted to help. “Not everyone is as lucky as I am,” she said. “This cookbook idea gave children an opportunity to help other, less fortunate kids.” After collecting a large stack of recipes and personal notes from other students, Chelsea sorted each recipe into a category and typed the manuscript. She designed a cover, acknowledgment page and table of contents, then printed several sample copies and started taking book orders. “On my first day I raised $100,” Chelsea reported, and has since collected a total of more than $800. She plans to continue distributing the original “Kids for Kids” cookbooks for a donation of $5 each as long as there is an interest. She also is planning a new volume for the 2001-02 school season.
