What place is the "9" in?

• ones

• tens

• hundreds

• tenths

• hundredths

Multiple Choice

Round to the nearest ten:
76

• 70
• 74
• 75
• 80

Multiple Choice

Round to the nearest hundred:
276

• 200
• 250
• 275
• 300

The process is the same when rounding after the decimal point,

except zeros at the end are not necessary

In this example, the 9 rounds up to 10, the zero goes in the tenths place and everything below it becomes a zero.

The 1 is carried over to the ones place

• 135.695

• 136.7

When directed to round a certain number of places, this is the number of digits after the decimal point.

In this example the number in the third place is 7. The number after it is bigger than 5, so the 7 goes up by 1.

When directed to round to the nearest "whole number" or nearest "integer"

This is the same as rounding to the ones place

Rounding is an important skill and is used to more simply represent solutions.

It is important to read and follow rounding directions in the problem, however avoid rounding until you have your final solution.
