Watch: Watch whether the learner checks the color of each card and assigns all 24 cards exactly once; a complete response has every red card inside and every yellow or blue card outside.

Misread: A learner may sort by the noun “shape cards,” by card size, or by the ring’s circular shape instead of acting on the color rule; correct counts with swapped identities still show a membership misread.

Curriculum: This task uses a one-set membership partition: a fixed finite universe is classified by the predicate “color is red.” The scored skill is applying one categorical rule item by item to build a complete, disjoint inside/outside classification.
