The ability to identify and manipulate 3D (three-dimensional) shapes is an important part of mathematical development.
It helps children understand the world around them.
Two dimensional shapes only have length and height which makes them look flat. But 3D shapes also have width as dimension and take up space.
Understanding 3D shapes help children develop spatial awareness, problem-solving skills, and logical thinking that they will need in math.
One of the best ways to explain the concept of 3D shapes to students, especially young ones, is to give examples by showing them everyday objects, like the following:
– sphere: ball
– cube: toy box, dice
– cylinder: cookie cans
– cone: party hat, traffic cone
– pyramid: tent
You can then ask your student to draw the shapes on paper. And then ask them to compare the differences between a real-life ball and a ball that they drew on paper. How do they make a shape on paper look more 3D?
A second way to help students to build a deeper understanding of 3D shapes is to have them make a 3D shape out of paper!

After making their 3D shape, have a guided discussion with your student. You can teach them math terminologies like faces, vertices, and edges.
Teaching 3D shapes through this hands-on activity is a great way to engage your student and an excellent opportunity to have them absorb the lesson.
Have fun!
