Registration for the 21 day challenge begins on January 11 and runs until January 24. Schools in North Dallas are trying to eat a healthy snack each day from January 25 to February 14. FISD is competing against Lewisville School District to see which district can have the most participants. FISD is also having a competition with each other for the campus that has the most participation. Anderson got second place last year with Curtsinger coming in first place. Help your child by registering them and helping them to have a healthy snack each day!
