Assess young students' ability to apply simple sorting rules to everyday classroom and household items by categorizing common examples (clean paper, plastic bottles, food scraps, soiled napkins, cardboard, and snack wrappers) into recycling, compost, or trash; require brief, age-appropriate justifications and adherence to basic local guidelines (e.g., recyclables must be clean and dry, food goes to compost) to promote reasoning and practical decision-making.
