Answer key and marking scheme
26–31
Fluent in angles on a line, including unfamiliar contexts.
20–25
Reliable on routine items; reasoning mostly sound.
12–19
Secure with support, inconsistent without it.
0–11
Re-teach the core rule before moving on.
Teacher notes
- Use the recognition block as a two-minute entry ticket; it tells you who is ready for angles on a line.
- Anything below 19 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 Angles on a Line worksheet for targeted written practice.
Common student mistakes
- Confusing angles on a line with a neighbouring idea in geometry.
- Treating every idea in geometry as the same skill.
- Reaching for a rule that belongs elsewhere in geometry.
What to do next
- Score below 12: work the Easy quiz, then the practice worksheet.
- Score 12–23: retake as a Timed Quiz to build fluency.
- Score above 23: move to the Challenge Quiz or the next subtopic.
- Ask the AI Tutor to re-teach any question you got wrong twice.
