Place Values – Why do we need to know them?

Rounding –how do we do it and why?

Steps to rounding:

  1. Find the place value you are asked to round to.
  2. Look to the right of that number
  3. If the figure is less than 5, keep the number before it unchanged and fill the rest of the number with 0’s
  4. 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.

How do we represent larger than or greater than and less than or smaller than?
