PLACE VALUE CHART ________ ______ ______ . ______ _______ _______ _______ _________ EXPANDED FORM = listing out the value of each digit in a number 564 = 500 + 60 + 4 134.32 = 100 + 30 + 2 + .3 + .02 4567.802 = 4000 + 500 + 60 + 7 + .8 + .002 ROUNDING DECIMALS Round 76.285 to the nearest hundredth. Underline the place value that you are rounding. Box in that underlined number and one number to the right of it. If the number to the right is 5 or greater than 5 - then the underlined number goes up by one. If the number to the right is 4 or less than 4, then the number STAYS the SAME. Round up or leave the number the same writing above original number. All of the numbers to the left stay the same, and all of the numbers to the right turn into 0. ESTIMATING DECIMALS *Estimating should make your job of solving problem QUICK AND EASY!! *Make sure your answer is REASONABLE - meaning that the answer actually makes sense!!! DO NOT confuse rounding with estimating!! Examples: $45.97 + $51.87 = 73.42 x 24.99 = 63.87 divided by 2.45 = COMPARING AND ORDERING To compare decimals you need to compare the numbers in each place value spot – this can be done if you line up the decimals and use zeros as place holders if needed. Compare from LEFT TO RIGHT.
