Assess early learners' ability to apply simple sorting rules by placing common household items into recycle, compost, or trash bins. Present 8–10 pictures or short descriptions (e.g., paper cup, banana peel, aluminum can, yogurt cup, soiled napkin, cardboard, broken plastic toy, apple core) and ask students to choose the correct bin and give a one-sentence reason using rules (clean/dry recyclables, organic compostables, non-recyclable trash). Include teacher prompts and brief formative feedback suggestions.
