Mathematics Class 6: Nets of 3D Shapes

The video tutorial by Kak Citra introduces 6th-grade students to the concept of 3D shapes and their nets. It begins with an overview of 3D shapes found in everyday life, such as tents, cans, and balls. The lesson then explains how nets are formed by cutting along the edges of these shapes. Detailed examples of nets for cubes, cuboids, pyramids, prisms, cylinders, and cones are provided, showing how they can be folded back into their original 3D forms. The video concludes with a recap and encourages students to practice creating these nets themselves.
