For more than 35 years, the St. Jude Math-A-Thon has been benefiting St. Jude Children's Research Hospital. The Math-A-Thon has been America's largest education-based fundraiser. To participate, students in Mrs. Merriman's Classroom ask family and friends for pledges to solve math problems in the St. Jude Math-A-Thon Funbook, developed by Scholastic.
