Math: Rounding Numbers

In Mrs. Dawson's math group we learned about rounding numbers to the nearest 10, 100 or 1000.

Remember the rule:

0-4 Round DOWN

5-9 Round UP

Round to the nearest 10:
37 becomes 40 (We look at the ones column.  The number is 7, so we round up).

Round to the nearest 100:
819 becomes 800 (We look at the tens column.  The number is 1, so we round down).

Round to the nearest 1000:
1999 becomes 2000 (We look at the hundreds column.  The number is 9, so we round up).

Here is a link to a rounding game that will help you practice:
