Rounding numbers is often done on purpose to obtain a value that is easier to write and handle than the original value.
As usual, the most basic form of rounding is to round a number to nearest tens. The basic requirement to do the task is the knowledge of skip counting by 10's and place value to tens.
Rounding a number to nearest tens: As already said above, to round a number to nearest ten is the most basic form of this skill. To do the task, kids should know the following;
10, 20, 30, 40, 50, 60, 70, 80, 90, 100, 110, and so on.
Which is skip counting by 10's. Once kids know above skip counting by 10's then it is very easy for them to round a given number to its nearest ten.
For example; consider we have 17 and we want to round it to nearest ten. To do the task, find two tens (from 10's skip counting) which have 17 between them.
These two tens are 10 and 20. The next step is to see, which 10's is closer to 17. Is it 10 or is it 20?
Of course it is 20 because it is just 3 numbers away from 17 compared to 10 which is 7 numbers away from 17. Hence, 17 rounded to nearest 10's is 20.
