Understanding Decimals: Comparison and Ordering

What is the main focus of the lesson introduced in the video?

• Multiplying decimals

• Comparing and ordering decimals

• Dividing decimals

• Adding and subtracting decimals

When comparing decimals, what is the first step according to the video?

• Compare the tenths place

• Line up the decimal points

• Compare the hundreds place

• Add zeros to make them equal length

In the example comparing Cloud Peak and Boundary Peak, which decimal place determined the greater height?

• Tenths

• Hundredths

• Thousandths

• Ones

What is the purpose of using a place value chart in comparing decimals?

• To add decimals

• To visualize and compare each place value

• To subtract decimals

• To multiply decimals

In the comparison between Cloud Peak and Wheeler Peak, which decimal place was crucial?

• Tenths

• Hundredths

• Thousandths

• Ones

What is the first step in ordering decimals from least to greatest?

• Compare the thousandths place

• Add zeros to the end

• Line up the decimal points

• Compare the ones place

Which mountain had the greatest height in the ordering example?

• Mount Rainer

• Mount Everest

• Mount Harvard

• Mount Whitney

In the practice exercise, what is the correct order of the numbers from greatest to least?

• 1.456, 1.32, 1.321, 1.383

• 1.321, 1.32, 1.456, 1.383

• 1.456, 1.383, 1.321, 1.32

• 1.32, 1.321, 1.383, 1.456

Why is it important to line up decimal points when comparing decimals?

• To add zeros to the end

• To make the numbers look neat

• To make the numbers longer

• To ensure digits of the same place value are compared

What should you do if a decimal number has fewer digits than another when comparing?

• Round the longer number

• Add zeros to the beginning of the shorter number

• Add zeros to the end of the shorter number

• Ignore the shorter number
