3-D Shapes - PowerPoint

In a vibrant PowerPoint presentation designed for Year 2 students, the topic of 3-D shapes is explored in a fun and engaging way. The aim of the lesson is for students to learn how to identify and describe three-dimensional shapes, as well as to discover the two-dimensional shapes that make up the faces of these 3-D forms. The presentation starts by defining a 3-D shape as a solid figure composed of faces, edges, and vertices (or corners). It then delves into examining various 3-D shapes such as cubes, cuboids, triangular prisms, square-based pyramids, spheres, cylinders, and cones, prompting students to count and record the number of faces, vertices, and edges each shape possesses.

The lesson continues by highlighting that some 3-D shapes, like spheres, cylinders, and cones, have curved surfaces in contrast to the flat faces of cubes and prisms. For instance, a cube has 6 faces, all of which are squares, 8 vertices, and 12 edges, while a sphere has 1 curved face, no vertices, and no edges. The interactive element of the PowerPoint invites students to click and reveal the 2-D shapes hidden within these 3-D objects, such as identifying the squares on a cube or the circles at the ends of a cylinder. Accompanying worksheets are provided for students to name the 3-D shapes and note down their properties, as well as to draw the 2-D shapes they can find on the surfaces of the 3-D shapes, reinforcing their understanding of the relationship between the two.
