Imagine you have a piece of land, like a big square shaped cookie. When you want to play a game with your friends, you want to make sure that everyone has a fair amount of space to play in. So you take your big cookie and draw a line down the middle with frosting, creating two equal parts.
Now, you and your friend stand on opposite sides of the cookie, each on your own side of the line. This is called division. You can only play on your side of the cookie, and your friend can only play on their side. This means that you both have the same amount of space to play in and nobody is hogging all the space.
Sometimes, if you have a lot of friends who want to play, you might need to divide your cookie even more. You can draw more lines with frosting to create even smaller parts, so that everyone has a piece of the cookie to play on.
In the same way, when people play sports or games on a field, they also need to make sure that everyone has a fair amount of space to play in. So they divide the field into different parts, just like how you divided your cookie. This way, everyone can play on their own side of the field and nobody is playing on someone else's side.
