Estimating And Rounding

To estimate you would have to round to the nearest 1's, 100's, 1000's etc.

To know what number to round just round to the nearest numbers it says on the paper and once you figure that out then you have to look at the right (beside your number).

If your numbers are 5 to 9 the you would have to round it up, but if it is 1 to 4 then you would have to round down.

For example.....


Estimating with Decimals


Its just like the same thing but its just with decimals. But this time you have to round to the nearest tenth's, hundredth's, thousandth's etc.

You just have to remember 5 or higher your have to round up, but if its 4 and lower then round it down.
