IntroduceLet’s review the rounding rules. According to
the song, what is the first thing that you do? Second? Last?
Look at the following dollar amounts and round to the nearest whole dollar:
$56.75$32.42$22.63$18.35
Rounding decimals like these can be used to estimate sums and differences.

TeachLook at this decimal4.56
What place value do you look at when you round to the nearest whole number? What number is it in this decimal?
Is the digit in the hundredths place important when rounding to the nearest whole number? Why or why not?
How do you think rounding decimals can help you estimate sums and differences?

Rounding Decimals
6.50 – 78.95 – 97 + 9 = 16 miles
To estimate the sums and differences of decimals, round each decimal to the nearest whole number. Then add or subtract.
