GA Milestone Review - Comparing Decimals

Monday, March 29

Decimal Place Value

• We use decimals to represent part of a whole.

• A decimal becomes larger as it gets closer to 1 whole.

• We often see decimals when representing money, so it may help to imagine decimals as money.

• We can add a 0 to the end of any decimal and it does not change the value.

When Reading a Decimal...

• Say the regular whole number that you see (don't say 0 if it is in the ones place).

• Use the word "and" to represent the decimal point (don't say and if there is only a 0 before the decimal point).

• Say the number after the decimal point with the place value that the last digit is in.

We can compare decimals using place value models.

Multiple Choice

• 40 > 4

We can compare decimals using a place value chart.

• Line the numbers up on the chart.

• You may add 0s to the ends of your decimals so that your decimals will have the same amount of digits.

• Begin with the largest place value (on the left) and move one space at a time to the right to compare the digits.

Multiple Choice

Quick Check: Compare 0.45 and 0.9.

• 0.45 = 0.9

• 0.45 < 0.9

• 0.45 > 0.9

We can compare decimals using a number line.

• The smaller decimals will be to the left on the number line.

• The larger decimals will be to the right on the number line.

Multiple Choice

Quick Check: Use a number line to compare 0.58 and 0.7.

• 0.58 = 0.7

• 0.58 > 0.7

• 0.58 < 0.7
