Today was review for the classes. They worked very hard rounding last year and most of them had no trouble at all remembering the steps. To help, we added a page to our journal:
However, we did have a minor twist to our rounding.... we were rounding decimals. There is no difference really, just a difference in the last line of the poem, "Everything after is a zero, not more."
When working with decimal numbers, you DO NOT have to have the zeroes after the decimal point. You can just drop them... For example:
rounded to the nearest thousandth is
(notice we dropped the last two digits)
It just takes getting a little used to. It is perfectly fine to keep the zeroes, it is just not efficient or a common practice in mathematics.
The assignment was "End Zone Mischief".
- Finish "End Zone Mischief"
