Limpiemos nuestra escuela (Cleaning Our School)

A big, summer storm left the school in this book a mess! The students, parents, and other volunteers worked to clean it up. They make teams to pick up aluminum cans, plastic bottles, and glass. After everything is cleaned up, they use graphs to show how much of each item they collected. They take these items to be recycled. They use the money they earn to help build a new playground. What does your school need, and how can you help?
