Common mistakes
The misconceptions stored on this entity, with the correction to give.
Students treat complex arithmetic as a rule to memorise rather than a relationship to understand.
Correction: Anchor the rule in a visual model first, then abstract it — the model is the explanation.
Learners apply the correct method to complex arithmetic but ignore the context or units.
Correction: Require an answer sentence with units on every applied question.
Teacher tips
