Assess a young learner's ability to evaluate and compare short sequences of visual code blocks (e.g., move, pick, place, rotate, repeat) to determine which sequence enables a simple robot to build the most stable tower using the fewest steps. Scope includes predicting final stability, counting and comparing step counts, identifying unnecessary or risky moves, and justifying the most efficient safe sequence; intended for early learners using block-based coding or a simple robot mat to develop evaluative reasoning.
