Rounding is an important skill that allows you to come up with an answer that’s *around* or *about* what the precise or accurate answer would be. Rounding also helps perform mental math and rationalize with what answer is best fit. Take this scenario for example. When Brandon shops he likes to spend around $150 every two weeks. The first two weeks of the month he spent $141 but the next two weeks he spent $148. Which weeks was closer to spending exactly $150, the answer is the second two weeks because when rounding to the nearest ten, if the ones place exceeds 5 you round up one in the tens place.

__Follow these steps to round to the nearest 10:__

1. Decide which number you are rounding- 434

2. Are you rounding to the nearest 10 or 100? In this case we will round to the nearest 10.

3. Take a look at the number in both the ones and the tens place… **4 3 4**

4. If the number in the ones place is 4 or less you let the number in the tens place rest(it does not change)

5. If the number in the ones place is five or more you raise the score (you add one more to the number in the tens place)

5. Lastly, the one’s place becomes a 0.

**6. Your final answer would be 430, rounded to the nearest 10.**

__Follow these steps to round to the nearest 100:__

1. Decide which number you are rounding- 571

2. Are you rounding to the nearest 10 or 100? In this case we will round to the nearest 100.

3. Take a look at the number in thes ones, tens, and hundreds place… **5 7 1**

4. If the number in the tens place is 4 or less you let the number in the hundreds place rest(it does not change)

5. If the number in the tens place is five or more you raise the score (you add one more to the number in the tens place)

5. Lastly, the tens and the ones places become a 0.

**6. Your final answer would be 600, rounded to the nearest 100.**

Rounding can be difficult, it’s important to follow the steps exactly and take your time. When you get the hang of it, it will become second nature. Remember to pay attention to what you are rounding to, nearest 10 or nearest 100.
