Comparing Decimals Effectively

The video tutorial explains how to compare and order decimals by stacking them. It emphasizes the importance of aligning decimal points and provides examples to illustrate the process. The tutorial covers comparing decimals like 1.32 and 1.5, and ordering a set of decimals from greatest to least, such as 1.42, 1.4, 1.5, and 1.38. The key takeaway is to stack decimals without moving the decimal points to accurately compare and order them.

What is the first step when comparing and ordering decimals?

• Multiply the decimals

• Stack the decimals

• Subtract the decimals

• Add the decimals

Which of the following decimals is greater: 1.32 or 1.5?

• Cannot be determined

• They are equal

• 1.5

• 1.32

Why is 1.5 greater than 1.32?

• Because 1.5 has more digits

• Because 1.5 is like $1.50 and 1.32 is like $1.32

• Because 1.32 is a smaller number

• Because 1.32 is less than 1.5

What should you do after stacking the decimals?

• Add zeros to the numbers

• Compare the whole numbers

• Circle the first place value

• Move the decimal points

When comparing 1.32 and 1.5, which place value do you compare first?

• Thousandths

• Ones

• Hundredths

• Tenths

If the digits in the ones place are equal, what should you compare next?

• The digits in the tenths place

• The digits in the hundredths place

• The digits in the thousandths place

• The digits in the tens place

Which of the following is the correct order from greatest to least: 1.42, 1.4, 1.5, 1.38?

• 1.5, 1.4, 1.42, 1.38

• 1.38, 1.4, 1.42, 1.5

• 1.5, 1.42, 1.4, 1.38

• 1.4, 1.42, 1.5, 1.38

What is the smallest number among 1.42, 1.4, 1.5, and 1.38?

• 1.5

• 1.38

• 1.4

• 1.42

If two decimals have the same digits in the tenths place, what should you compare next?

• The digits in the thousandths place

• The digits in the hundredths place

• The digits in the tens place

• The digits in the ones place

What is the correct order from least to greatest: 1.42, 1.4, 1.5, 1.38?

• 1.4, 1.42, 1.5, 1.38

• 1.38, 1.4, 1.42, 1.5

• 1.5, 1.42, 1.4, 1.38

• 1.5, 1.4, 1.42, 1.38
