Misconceptions
Stored on the entity so worksheets, quizzes and lesson plans all target the same known errors.
Students treat adding decimals 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 adding decimals but ignore the context or units.
Correction — Require an answer sentence with units on every applied question.
