Remember

The places right of the decimal point are tenths, hundredths and thousandths.
Expanded form shows each digit times its place value, such as 4 × 1/10.
To compare decimals, compare digits from left to right, one place at a time.
Adding zeros to the end of a decimal does not change its value: 0.3 = 0.30.
Round up when the next digit is 5 or more; keep the digit when it is 4 or less.

Common mistakes with this 5th grade comparing decimals quiz

Students choose the decimal with the most digits as the greatest. Instead, compare place by place from the left.
Students round up when the next digit is 4 or less. Also, only digits 5 and above round up.
Students choose an answer that is correct for a different place. Instead, read the rounding place twice. Slow down at that step and check it twice.
Students pick a list that is out of order. Also, add zeros and compare each neighboring pair. Slow down at that step and check it twice.

Tips to get a high score

Add zeros to match lengths before you compare. This one step removes most mistakes. Repeat this habit on every problem for the best results.
Underline the rounding place and circle the next digit. Then decide whether to round up or stay. Repeat this habit on every problem for the best results.
Teachers can use the race question as a short debate on why a smaller time is faster. Repeat this habit on every problem for the best results.

5th grade comparing decimals quiz: frequently asked questions

How do you read 0.46 in words?

Say forty-six hundredths. The last digit sits in the hundredths place, so the whole decimal is read as a number followed by that place name. The same method reads 0.462 as four hundred sixty-two thousandths.

How do you tell whether two decimals are equal?

Add zeros at the end until they have the same length, then compare. Since 1.50 and 1.5 are the same amount, zeros at the end of a decimal do not change its value.

How do you choose the number that rounds to a target?

Find the range of numbers that round to the target. For a target of 3.2 at the nearest tenth, the number must be from 3.15 up to just under 3.25. Test each choice against that range.
