Circles

In this video, we will learn how to identify circles regardless of their orientation, size, or color. Circles can come in many different colors and sizes. How can we tell if a shape is a circle? We know that circles are 2D shapes. What else do we know about circles? They are round. How do we draw a circle? A circle is a continuous curve.

There are lots of examples of circles in real life. A doughnut is a circle, and the hole in the center of the donut is also a circle. This part of the frying pan is a circle. This pizza is also a circle, and so are the slices of pepperoni on top. Circles are all around us. See how many you can spot. Let’s try identifying some circles with some practice questions.

Choose the circle.

We’re shown five different 2D shapes, and we have to choose the circle. Let’s think about what we know about circles. We know a circle is a 2D shape, but all of these shapes are 2D shapes. What else do we know about circles? We know that circles are round. Which of our 2D shapes is round? It’s this one right at the bottom. This is the only 2D shape we can see which is round. This is the circle. All of the other shapes have straight sides. We chose the circle.

How many circles are in this picture?

We’re showed a picture of a train. It’s being made from lots of 2D shapes. We have to count the number of circles in the picture. How many circles can you see? The wheels of the train are made from circles. Here’s one, two, three, four. There are four circles in this picture of a train.

What have we learned in this video? We’ve learned how to identify circles. We’ve learned that circles are round, and they can come in different sizes or colors. They’re still circles.
