The "Exploring Geometric Operation Materials" box contains a yellow cone, a red cylinder, and a set of yellow rectangular flat plates. Students can intuitively explore the cross-sections and unfolded diagrams of geometric bodies, and easily play with the geometric world from two-dimensional to three-dimensional with just one box. During the teaching process, teachers can use this teaching tool to guide students to carefully observe the shapes and structural characteristics of cones and cylinders, and thus master the features of geometric shapes. By hands-on combination, students can gain a deeper understanding of the derivation process of the surface area formula and effectively cultivate spatial transformation thinking.
