Watch: Watch whether the learner checks the whole equation after making two valid digit shapes; decisive evidence is one conserved move whose final board makes both sides equal 18.

Misread: A learner may read “segment” as any stroke, “move” as add, remove, or edit a sign, or think the final equation alone is the answer. The required response is one occupied digit segment moved to one empty digit slot, with both endpoints and the true equation recorded.

Curriculum: This task develops structural reasoning with seven-segment digit representations, conservation under a one-part relocation, and equality as a relation between whole-number expressions. The scored skill is constructing and validating a complete move witness, not recognizing a puzzle picture.
