Teaching Notes
Use the worked example and teaching sequence below to explain the reasoning before independent practice.
Before You Begin
- Recognize heavier and lighter.
Teaching Steps for Parents and Teachers
- Compare the stated weights in the same unit, or read a balance.
- On a balance, the lower side is heavier.
- Use the requested comparison word.
Worked Examples
A weighs 4 units and B weighs 7 of the same units. Which is lighter?
- Compare 4 and 7.
- 4 < 7.
Answer: A
Common Mistakes and How to Help
Size alone does not tell which object is heavier.
Are both weights expressed in the same unit?
Questions to Check Understanding
- Are both weights expressed in the same unit?
- What in the numbers or diagram supports your answer?
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.
