Rounding

When rounding, use the following steps as a guide.

Step 1:

Circle the place value of the digit to be rounded. This is the rounding digit.

Step 2:

Look to the neighboring digit on the right.

Step 3:

a) If the neighboring digit is less than five (0 - 4), keep the rounding digit the

same. This is called rounding down.

b) If the neighboring digit is five or greater (5 - 9), increase the rounding digit

by one. This is called rounding up.

Step 4:

a) When rounding to the left hand side of the decimal, all digits to the right

side of the rounding digit will become 0 up until the decimal point.

b) When rounding to the right hand side of the decimal, drop all digits to the

right of the rounding digit.

stays the same.

Step 4:

Everything to the right of the thousandths place value gets cut off.
