What are 3D Shapes?

What makes something 3D? Is it the way it looks? An easy way to think of a 3D shape is any shape or object that takes up air space. Think about your own body for a minute. Your body is a 3D shape. It is not a uniform shape, like a building block, but it is a 3D shape, nonetheless. What makes your body a 3D shape? Does it take up air space? Of course it does; you can't be at the same spot as anyone else. You can't take up the same space as a chair or a dog or anything else. Only you can occupy your space. This is what makes a shape 3D.

A test you can do to check whether something is 3D or not is to try to place something in the exact spot where that shape is. Look around you for something you can grab. Take your pen, for instance. Place it on your desk. Now, try and take another pen and place it in the same exact spot as your first pen. Can you do it? No, you can't. The only way you can do it is if you moved your first pen to make room for the second.

Even a flat piece of paper is a 3D shape in the world. Lay two pieces down, one on top of the other, and look at them. Are both sheets of paper taking up the same space? It may seem so at first, but look carefully. One is actually on top of the other because both take up space.

In mathematical terms, a 3D shape has three dimensions. The D in '3D' stands for dimensional. In a world with three dimensions, you can travel forwards, backwards, right, left, and even up and down. The ability to travel up into space and back down differentiates 3D from 2D. The world you live in is all 3D. You can walk anywhere on land and you can fly anywhere in the air. Underwater, you can swim in all three dimensions.

Examples of 3D Shapes

In mathematics, you have your standard 3D shapes that you need to know. These are shapes such as cylinders, spheres, cubes, and pyramids.

2D Shapes Definition

'2D' stands for 2-dimensional. A 2D shape is any shape that has two dimensions. Think about what it means to have two dimensions for a moment. If we had only one dimension to work with, we could only move backwards or forwards in a line. A line is one-dimensional. If we had two dimensions, on the other hand, we could go forwards and backwards in a line and turn in any direction to start a new line. We are essentially able to travel anywhere on a flat surface. In mathematics, a flat surface is called a plane. A plane is one example of a two-dimensional shape. A plane is essentially the largest sheet of paper you will ever find. In fact, it is a sheet of paper so large that it never ends. One way of thinking about 2D shapes is anything that lays flat on a piece of paper.

Take out a piece of paper, and place it on your desk. Notice how flat it is. Now take any nearby object, place it on your piece of paper, and trace around it. Look at your shape. What does it look like? Congratulations, you have just drawn a 2D shape! This is another way you can think of 2D shapes: 2D shapes are any shape you can trace from an object on a flat piece of paper.

Take a cube and trace it on a piece of paper and you will get a square shape. Take a soda can and trace it on a piece of paper. Depending on how you lay the soda can down, you will get either a circle or a rectangle. Try it out and see for yourself.

We have been working away at this for quite sometime now, about five years. Not many people even know that we exist. We now have tons of new printable math worksheets that cover just about every topic in the CORE curriculum. Please let us know if we have missed any topics. We aren't just a mill of endless problems. We provide detailed step-by-step walk-throughs to help teachers, parents, and tutors job's much easier. Let our work make your work easier and quicker.

UPDATE: The average member of our site reports that they save 12-hours of preparation each work week. With a 40-week work schedule that is just over 480 hours (20 days) of time saved by an average member. What would you do with an extra 20 days of time every year? Mostly likely, it would relieve a good deal of stress for you. What are you waiting for,become a member now!

Fraction Circle or Square

Percentage Fraction Decimal Grid Updated!

Divide a square or circle up into a number of parts.

The slices or rectangles can be painted various colors and these colors then represented as either decimals, fractions or percentages.

Launch

Sierpinski like triangle

Fractal Explorer

The fractal explorer shows how a very simple pattern, when repeated can produce an incredible range of images. From organic tree like structures to rigid geometric forms.

Fun to use and lots of mathematical concepts involved.

Launch

A Subtraction Fact

Addition & Subtraction Facts

Teaches addition and subtraction facts up to twenty using animated penguins.

The penguins jump between two icebergs to show addition facts for the given total. For subtraction facts the penguins dive off the iceberg into the water below.

A number line represents the number facts.

Launch

π & circle area

Explore PI

This interactive demonstration shows firstly how pi relates to the circumference of a circle. This is achieved using a regular polygon approximation, the closed polygon is opened to reveal this magical number.

The area of a circle π r ² is also explained using animated slices.
