Building with 3D Shapes: Provide students with a variety of 3D shapes such as cubes, cylinders, cones, and spheres. Ask them to use these shapes to build different objects or structures. For example, they can build a house using cubes for the walls, cylinders for the columns, and cones for the roof.

Shape Hunt: Take students on a shape hunt around the classroom or school. Provide them with a list of 3D shapes they need to find, such as a sphere, cube, cylinder, and pyramid. They can search for these shapes in different objects or items around them and mark them off on their list.

Sorting 3D Shapes: Give students a collection of 3D shapes and ask them to sort them into different categories based on their attributes. For example, they can sort them into groups of shapes with flat faces and shapes with curved faces. They can also sort them based on the number of edges or vertices. This activity helps them understand the different characteristics of 3D shapes.
