When Jessica was young, she participated in her school's Math-A-Thon. Her mom, Allison, a teacher, always felt they were helping the kids featured in the Math-A-Thon Funbook. But the summer Jessica turned 9 years old, she was found to suffer from acute lymphoblastic leukemia, the most common form of childhood cancer, and the family's perspective changed. Every dollar raised by Math-A-Thon was going to help kids just like Jessica.
