Problem: Books slid off when Maya carried them to the rug. At the building station, Maya and Chen built a tray model from a shallow box. Materials: shallow box, cardboard strips, tape. Shape features: they added raised edges on all four sides. They tested it by putting books on the tray and walking. The books stayed on the tray and did not slide off. The edges acted like walls to keep items in. The model showed the shape helps the tray work. How did the edges help when they tested it?
