Teaching Notes
Use the worked example and teaching sequence below to explain the reasoning before independent practice.
Before You Begin
- Use a ruler and recognize centimeters.
Teaching Steps for Parents and Teachers
- Estimate using a familiar benchmark.
- Measure from the zero mark with the correct unit.
- Compare the estimate with the measured length.
Worked Examples
A book was estimated to be 20 cm long and measured 23 cm. Find the difference.
- Both measurements use centimeters.
- 23 − 20 = 3.
Answer: 3 cm
Common Mistakes and How to Help
An estimate is a reasonable prediction, not an exact measurement.
Was the estimate reasonable compared with the measurement?
Questions to Check Understanding
- Was the estimate reasonable compared with the measurement?
- 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.
