Rounding

Rounding is a skill in maths that usually use addition and division. Rounding means to circle the nearest ten, hundred, thousand, and more.

Addition and divison are both strategys the are used for rounding. To round, the person needs to find the mean, to find the mean get a set of numbers like 12346 then, add all of the numbers, 16 is the answer. 

After, divide the number by the amount of the numbers you've got so, 16 divided by 5 is 3.1. So 3.1 is the mean.

Here comes the rounding part comes in so if the numbers are 5-9 they are called high five and the numbers that are 1-4 they are called four floor. Look for the last digit, so 1 will be in the four floor after, you round it to the nearest ten so 1 became a zero because it rounds to the nearest ten, so the final answer will be 3.

Rounding can help people to add and divide to make maths easy or hard depending on what level you are.
