By following this method and using simple column subtraction, students can easily solve the problem and arrive at the correct answer of 0.24.

Subtracting decimals is a fundamental skill in mathematics that builds upon students' understanding of place value and basic arithmetic operations. This collection of examples helps teach the topic by providing clear, step-by-step visual representations of the subtraction process. Students can observe how to align decimal points and perform the subtraction column by column, reinforcing their understanding of place value in decimal numbers.

Offering multiple worked-out examples is crucial for students to fully comprehend the concept of decimal subtraction. Each example in this collection showcases different scenarios, from simple subtractions without regrouping to more complex ones that require it. By exposing students to various problem types, they can develop a comprehensive understanding of the process and gain confidence in their ability to subtract decimals accurately, regardless of the complexity of the problem.

Teacher's Script: Let's look at our fourth example of subtracting decimals. We have 0.77 minus 0.53. Remember, when subtracting decimals, it's crucial to line up the decimal points. This ensures we're subtracting hundredths from hundredths and tenths from tenths. Let's subtract column by column, starting from the right. In the hundredths column, 7 minus 3 equals 4. In the tenths column, 7 minus 5 equals 2. So, our final answer is 0.24. Notice how we didn't need to regroup in this example. Always double-check your work by making sure the decimal point is in the correct place in your answer.
