Rounding: Hundred Rounding numbers makes numbers easier to work with in your head. Round numbers will end with 0. It is an estimate or "about this much" - "About 200 students came to the game." Even though there were exactly 238. The column below (to the right of) the place value to round to will tell which number to round to. 1,2,3 & 4: Round down. 5,6,7,8,9: Round up.
 Directions: Round numbers to the nearest 100. Write the hundred below & the hundred above the given number. Circle which hundred you round to. Example: Round to the nearest hundred: 468 - The number line shows 400 as the hundred below 468 and 500 as the hundred above. Round up to 500. Or the place value next the hundreds is the tens. (468) 6 is in the tens & 6 says Round up to 500. Name _______________________________ Date: ________________________________ Score: ___________________________
