Place Values – Why do we need to know them?
Rounding –how do we do it and why?
Steps to rounding:
- Find the place value you are asked to round to.
- Look to the right of that number
- If the figure is less than 5, keep the number before it unchanged and fill the rest of the number with 0’s
- If the figure is 5 or greater, add 1 to the number that you are rounding to and fill the rest of the number with 0’s.
Ex: Round $567.32 to the nearest dollar.
Ex: Round $567.82 to the nearest ten dollars.
