Assess young learners' ability to sort and group everyday objects by color, shape, size, and texture to solve simple real-world problems. Tasks should require applying two or more attributes (e.g., "Find all small, smooth red items" or "Group blocks by shape and size to fill two boxes"), explaining grouping choices, and using comparisons (same/different, more/less) to make or revise groups. Include classroom- or home-based scenarios and short constructed responses.
