Snack Drive

This fall, second graders at Challenger School focused on Community Citizenship and Government in Social Studies. They learned about civic roles and organized a Snack Drive to support the PTA Angel Program, helping community members facing food insecurities. Students created a promotional video and posters for the drive, resulting in numerous healthy snack donations. This initiative emphasizes the importance of nutrition for better focus and learning in school.
