Assess students' ability to analyze and classify common classroom and household objects by primary material (wood, plastic, metal) and by function (toy, tool, utensil). Tasks include identifying the material and function of pictured or described items, sorting small sets into the correct categories, and giving a simple reason for each choice using observable properties (e.g., hard/soft, shiny/lightweight) and function clues (play, fix, eat). Scope: everyday items appropriate for Pre-K–Grade 2 with emphasis on observation, comparison, and clear justification.
