Common Mistakes and How to Help
Skipping a number or counting the starting number as the next step.
Say the sequence aloud one number at a time. What comes immediately after 3?
Questions to Check Understanding
- How does each number change?
- Which number comes just before the blank?
- Does your answer keep the sequence in order?
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.
