Comparing Decimals to Hundredths

This lesson focuses on comparing decimals to the hundredths place using number lines and place value charts. It addresses common misconceptions students may have, such as assuming longer decimals are greater or misapplying whole number place value knowledge to decimals. The lesson emphasizes the importance of correct place value understanding and provides strategies to help students make accurate comparisons.

What is the main objective of this lesson?

• To multiply decimals

• To add and subtract decimals

• To divide decimals

• To compare two decimals to the hundredths place

Which of the following decimals is greater: 0.53 or 0.35?

• They are equal

• 0.53

• 0.35

On a number line, where would 0.28 be in relation to 0.7?

• Cannot be determined

• To the right

• At the same point

• To the left

In a place value chart, which is greater: 0.29 or 0.74?

• They are equal

• 0.74

• 0.29

• Cannot be determined

Which number is greater: 1.35 or 1.3?

Why might students think 0.4 is greater than 0.88?

• Because 4 is greater than 88

• Because tenths are larger than hundredths

• Because 0.88 is a smaller number

• Because 0.4 has fewer digits

What is the incorrect comparison students might make between 0.25 and 25 tenths?

• 0.25 cannot be compared to 25 tenths

• 0.25 is less than 25 tenths

• 0.25 is greater than 25 tenths

• 0.25 is the same as 25 tenths

Why might students think 0 is greater than 0.42?

• Because 0.42 is a decimal

• Because 0 is a whole number

• Because 0 is in the ones column

• All of the above

What was the main method used to compare decimals in this lesson?

• Using multiplication and division

• Using addition and subtraction

• Using estimation

• Using a number line and place value chart
