Teacher notes

- Anything below 14 marks means the application stage needs re-teaching, not more practice.
- Project the whole-class version and poll answers before revealing the explanation.
- Pair the results with the Rounding Decimals worksheet for targeted written practice.
Common student mistakes
- Rounding from the last digit backwards instead of from the deciding digit.
What to do next
- Score below 9: work the Easy quiz, then the practice worksheet.
- Score 9–17: retake as a Timed Quiz to build fluency.
- Score above 17: move to the Challenge Quiz or the next subtopic.
- Ask the AI Tutor to re-teach any question you got wrong twice.
