What are three-dimensional models?

A three-dimensional model is like a toy block you can touch and move around, it has height, width, and depth, just like real things.

Imagine you have a cube, like the sugar cubes in your tea. If you look at it from one side, it looks like a square. But if you turn it around, you see all its sides, top, bottom, front, back, left, and right. That’s what makes it three-dimensional, it has three directions to explore!

Think of your favorite playground. A slide is not just flat like a piece of paper, it goes up and down too! If you made a 3D model of the slide with blocks, you could see how tall it is, how long it is, and even how wide it is. You could walk around it and touch all its parts.

A drawing on paper is like looking at a toy from just one angle, it’s two-dimensional. But when you build the toy with blocks or clay, it becomes three-dimensional, just like your playground slide!
