### Are You Teaching How to Estimate the Sums? Estimate the Sums
A quick way to estimate the sum of two numbers is to round each number and then add the rounded numbers. {See yesterday's post for help on rounding.} It is likely that this won't be the exact answer but it may be close enough for some purposes. Students need this mental math not only for future math classes and math procedures, but it is also a life skill. Were you over charged at the furniture store? Did you receive the correct amount of change back from the waitress?

How to estimate a sum by rounding:
• Round each number in the problem.
• Add the rounded numbers together, mental math is even better.
More reasons WHY you would use rounding to estimate the sum:
• Check to see if you have about enough money to buy something.
• Get a ball park idea if they have a correct answer to a problem. Is 500 an intelligent answer for 23 + 31?
