Crayola Products and International Paper have teamed up to reward school children for drinking milk.

Together they have launched the “Kids’ Power” themed milk cartons. The cartons feature creative messages, puzzles and brainteasers designed to inspire children’s creativity. Children can visit the Web site: to get puzzle answers and to participate in interactive online activities.

In addition to the fun for the kids, teachers can win Crayola art materials for their classrooms. By going to the Web site:, teachers can register to win a Crayola gift package worth more than $100. One winner will be drawn each week.

The program started on August 1 and will run for 40 weeks.
