Misconceptions
Stored on the entity so worksheets, quizzes and lesson plans all target the same known errors.
Confident students rush parallel and perpendicular lines and skip the checking step.
Correction — Build in an estimate-before-solve routine so an unreasonable answer stands out.
Learners over-generalise a special case of parallel and perpendicular lines to every situation.
Correction — Present a deliberate non-example and ask why the rule fails.
