Common mistakes
The misconceptions stored on this entity, with the correction to give.
Learners apply the correct method to introducing counterexamples but ignore the context or units.
Correction: Require an answer sentence with units on every applied question.
Confident students rush introducing counterexamples and skip the checking step.
Correction: Build in an estimate-before-solve routine so an unreasonable answer stands out.
