Rounding numbers:

We have used this rounding rhyme below to help instruct us on how to do this. Below is an example of how we use this in class.

63 rounded to the nearest 10 =   

Find the number in the Tens which is 6 (I ask the children to circle it), look next door in the Ones and it's a 3 (I ask them to underline it).        5 or higher add 1 more doesn't apply as 3 is less than 5, 4 or less let it rest applies because 3 is less than 4 so I let the 6 (that you circled) rest.  Numbers in front - there aren't any in this example, numbers behind zero's your name so we change the 3 to a 0.  The answer is 60.

68 rounded to the nearest 10 =

Find the number in the Tens which is 6 (I ask the children to circle it), look next door in the Ones and it's an 8 (I ask them to underline it).        5 or higher add 1 more applies as 8 is higher than 5, so I add 1 more to the 6 (that you circled) which is 7.  Numbers in front - there aren't any in this example, numbers behind zero's your name so we change the 8 to a 0.  The answer is 70.

If rounding to the nearest 100, do the same but you find the number in the hundreds column and circle it, look next door into the Tens and underline it.  You either add 1 more to the hundreds or let it rest.  Tens and Ones change to 00's.

Rounding to the nearest 1000 would be the same method, you find the number in the Thousands and circle it, look next door at the Hundreds and underline it.  Depending on this number you either add 1 more to the Thousands or let it rest.  Change the Hundreds, Tens and Ones to 000s.

Always check answers by asking yourself where the number would be on a number line and which 10's, 100's or 1,000s is it closer to.
