Teaching Notes
Focus: Subtracting Like Unit Fractions. Use the worked example and teaching sequence below to explain the reasoning before independent practice.
Before You Begin
- Read the numbers and identify the operation.
Teaching Steps for Parents and Teachers
- Use a common denominator so both fractions name the same-sized parts.
- Subtract the numerators in the stated order and keep that common denominator.
- With mixed numbers, you can first convert to improper fractions.
- Simplify the difference; if it is greater than one, read the equivalent improper and mixed forms together.
Worked Examples
5/7 − 2/7 = □
- Five sevenths minus two sevenths leaves three sevenths.
- Subtract 5 − 2 = 3 and keep the denominator 7.
Answer: 3/7
Common Mistakes and How to Help
The answer does not match the requested form or place.
Return to the worked example. Ask the learner to explain each step and check the result against the original question.
Questions to Check Understanding
- What does each number in this example represent?
- Why does the final answer have this form?
- Can you explain the same steps using another example?
Practice Advice
Work through the example together. Ask the learner to explain the first two problems, then try three independently. Review the first incorrect step before assigning more practice.
Next Practice
- Use New Numbers to practice the same skill with different values.
- If the learner needs help, return to the example and model each step before trying again.
