Assess young students' ability to observe, analyze, and classify everyday objects by color, shape, material, and use. Tasks require sorting objects (real or pictured) into single and overlapping categories defined by one or more attributes, explaining choices in simple spoken or written sentences or drawings, identifying items that meet or contradict category rules, and creating an original two-attribute sorting rule with justification. Scoring emphasizes accurate attribute naming, logical multi-attribute grouping, clear explanations of reasoning, and comparison of similar objects.
