3D Objects

Print Friendly, PDF & Email

We spent some time on Thursday building 3D objects using popsticks and playdough.  We have learnt the names and features of several 3D objects – pyramids, prisms, cylinders, spheres and cones are some of them.

We know that 3D objects have faces, edges and corners (or vertices) on them.  For example, a cube (which is also a prism) has 8 faces, 12 edges and 8 corners.  The faces of 3D objects are 2D shapes such as rectangles and triangles.
