Since we are rounding off to the nearest 100 we will look at the number to the right of hundreds which is the tens.
Now 5 is the key number. If it 5 or greater you round up if it is less than 5 that is 4 or lower you round down. When you round to the nearest 100 the numbers in the tens and one's places become zero, so 153 when rounded off to the nearest 100 will become 200.
Similarly, 175 rounds off to 200, 871 to 900 and 963 to 1000.
So, this was simple, you look at the number to the right of hundreds place, which is the tens number, if it higher than 5 rounds up and change the tens and one’s number to zero. And that’s it the number has been rounded off to the nearest 100. These rounding lessons further become helpful in the common core math multiplication and common core math addition. Therefore these concepts must be cleared at this stage.
Rounding can be a little difficult to understand. If your kids are having issues learning how to round up then read on to find out a simple way to round to the nearest 10 or 100. Rounding can be tricky this is the main reason why it is essential to learn and develop concepts at an early age.
So, the first step is to write the number you need to round off. Now underline name at the 100th place. The name which is on the tens place indicates that you need to round up or round down. The number on the hundredth place will be rounded off. One thing which you need to keep in mind is that look on the right of the amount which needs to be rounded.
