What are big round holes?

Big round holes are spaces that look like circles, just like the hole you make when you punch through a paper plate with your finger.

What makes them big and round?

Imagine you have a cookie, and you use a round cup to press into it, poof! You get a big round hole in the cookie, just like the one you might find on a pizza or a cake. These holes are often made by something round and strong, like a cookie cutter, a bite, or even a drill.

How do we use them?

Big round holes can be really useful! If you think of a donut, it's just a big round hole in the middle of a circle. Or imagine a wheel, if you take away the center part, that’s like a big round hole too. Even your ear has a little round hole called the ear canal, which helps you hear!

So next time you see something with a big round hole, think about what made it, and maybe try making one yourself!
