Assess Pre-K–Grade 2 students' ability to apply simple sorting rules to common household items by identifying whether pictured or described objects belong in recycling, compost, or trash. Include typical materials (paper, cardboard, plastic bottles, glass jars, food scraps, soiled paper towels), brief contamination guidelines (rinse containers, remove lids), and short scenarios asking learners to choose the correct bin and justify their choice in one sentence; allow for local variation notes.
