Sort Objects by Shape: Drag to Matching Grey Areas

This GeoGebra example demonstrates an interactive sorting activity where users drag various geometric objects (such as circles, rectangles, squares, ellipses, and prisms) into corresponding grey areas to classify them by shape. The core mathematical concepts involve basic shape recognition and classification in plane geometry, including circles, rectangles, squares, ellipses, and solid geometry prisms. The construction uses GeoGebra commands such as Point, Polygon, Circle, and Midpoint to create multiple objects (points A, B, C, D; polygons poly1 to poly4; and segments or circles a through p) and builds four grey target zones, each representing a specific shape category. This example is suitable for early elementary or kindergarten math education, fostering observation skills, shape identification, and classification logic, and can also serve as an engaging exercise for special education or interactive classroom settings.
