3. The trick is: If the NEIGHBOR is five or
more, add one more (to the place value you
are rounding to) or if the NEIGHBOR is 4 or
less just ignore (the place value you are
rounding to)
4. The neighbor (hundredths place) is a
seven, so what will happen to the tenths
place?
Round these numbers to the nearest

ForRounding
example: Round
to whole
the nearest
whole.
1. Look at the decimal number (seventy nine
hundredths)
2. Apply the same rule (5 or more, add one
more. 4 or less, just ignore)
3. Since the seven in 79 is greater than five,
the next place value (the ones-which is a
whole number) will round up
4. \$86.79 rounded to the nearest whole
would be \$87
Rounding to the nearest whole
Let’s try another one!
1. Look at the decimal number in the number.
2. Determine which place value would be the whole number
3. Apply the same rule (5 or more, add one more. 4 or less, just ignore)
• Round 6.8 pounds to the nearest whole
• Round 894.3 to the nearest whole
• 1,403.293 to the nearest whole
Closure
•On your slate, write the rules for
rounding we learned and another trick
