Estimating 2
Find the estmated number and match it to the original number. Remember: you estimate by finding the place value to be rounded; look at the number to it's right: if the number to it's right is between 0  4, then leave the rounded number as it is. If the number to it's right is between 5  9, then add +1 to the number to be rounded. All the digits after the rounded number change to zeros.
