Size

Size is how big or small something is. It's like comparing a big elephant to a small mouse. The elephant is much larger in size than the mouse. We can also use different units to measure size, like inches or centimeters. If you want to know the size of something, you need to measure it! This can be done with a ruler, tape measure or even just by counting how many of something there are. Understanding size is important because it helps us compare things and make decisions about what we want or need.
