•  COMPARING DECIMALS

1.  Line up the decimals.
2.  Fill in the empty spaces with zeroes.
3.  Start comparing at the highest place value.

Example:     456.489 ____  45.658947

456.489000
045.658947
4 is larger than 0, so the first number is greater (>).

ROUNDING DECIMALS

1.  Underline the place value of the digit you are rounding to.
2.  Look to the RIGHT of the underlined digit.
3.  If the number is 5 OR MORE, RAISE THE SCORE of the underlined digit.  4 OR LESS, LET IT REST (the underlined digit.)
4.    Everything AFTER the underlined digit FALLS OFF.

Example:      Round 47.856 to the nearest tenth.

1. Underline the tenths place.  47.856.
2. Look to the digit to the right of the underlined digit (5).
3. 5 or more means to raise the score, so the 8 becomes a 9.
4. The 5 and the 6 fall off.

ESTIMATING DECIMALS
1.  Remember, to estimate simply means to ROUND to the nearest whole number.
2.  Underline the ONES place and use the TENTHS place to round.

Example:     \$56.78

\$56.78
The 7 in the tenths place tells me to RAISE THE SCORE.
The 6 becomes a 7.  The number before the underlined digit stays the same and everything after falls off.

So, \$56.78 estimates to \$57
