When you think about a cookie, and you break it into two equal parts, each part is called a half. So, if you have one whole cookie and you split it into two pieces that are the same size, each piece is a half. Imagine you have a pizza. If you cut the pizza right down the middle, you get two halves. Each half is exactly the same size as the other. This is what makes it a half.

Now, let’s think about a sandwich. If you take a sandwich and cut it into two equal parts, each part is a half of the sandwich. It’s like sharing with a friend; you get one half, and your friend gets the other half, and both of you have the same amount to eat.

Think about a piece of paper. If you fold the paper in the middle, you divide it into two halves. Each side of the fold is a half of the paper. So, a half is just one of two equal parts of something, like a cookie, a pizza, a sandwich, or a piece of paper.
