STREAM Activity: 3D Shapes

Explore 3D shapes using a triangle!

Activity best for children ages 2 and up

Shapes are one of the first things we learn as a child. We then quickly learn how we can find shapes all around us. We first learn about 2D shapes, like when we draw a square on paper. But as we grow older, we learn about shapes in a different way from what we’re used to–3D shapes. If you were to draw a square on a piece of paper, that shape would be flat. Because it is a 2D shape, you wouldn’t be able to pick up the square you just drew. However, if we think of 3D shapes, like a cube of ice with more sides, would we be able to pick up that shape? Yes! Because ice cubes are 3D shapes, we are able to hold that object in our hand. The cool part about 3D shapes is that when we combine different shapes together, it can form a completely different shape or a similar one. Today, we are going to be exploring a few 3D shapes that all make the use of a triangle, along with other shapes. Let’s give it a try and make our own 3D Shape Set!

Math Connections

3D shapes are found everywhere, so math concepts, like measurement, are very important for the real world. We cannot build homes, which are a combination of different 3D shapes, without being able to determine the correct size and measurements.

Real World Connections

Most of the things on earth are made of 3D shapes. Being able to identity and put together different shapes to create different structures and sculptures is an important skill.
