A variety of objects (blocks, buttons, or cut-out shapes) in different shapes, sizes, and colors.
Sorting trays or containers..Provide each student with a variety of objects in different shapes, sizes, and colors.
Ask students to sort the objects into different trays or containers based on shape first (e.g., circles, squares, triangles).
Once sorted by shape, ask them to further sort each shape by size (e.g., small, medium, large).
Discuss the results with the students, reinforcing the concepts of shape and size.
