Think of mean like a way to share your toys fairly with your friends. If you have 10 toy cars and 5 friends, you want everyone to have the same number of cars. So, you count all your toy cars, which are 10, and then you share them equally among your 5 friends. Each friend would get 2 cars, because 10 divided by 5 is 2. The number 2 is the mean or average number of cars each friend gets.
Another way to think about mean is like baking cookies. If you bake 12 cookies and want to give them to 4 friends, you will give each friend the same number of cookies. First, you count all the cookies, which is 12, and then you divide them by the 4 friends. Each friend gets 3 cookies. So, 3 is the mean or average number of cookies each friend gets.
Lastly, imagine a mean as a balance scale. If you have different weights on each side, the scale tips. But if the weights on both sides are the same, the scale is balanced. The mean helps us find that balance by making sure everything is shared equally.
