The activity is called either as "Broad Stairs" or "Brown Stairs". It is a set of ten brown solid cuboids having same color and shape. The thickness is varied in each of them from one another exactly 10 mm. the thinest is of 10 mm and the thickest which is 100 mm in height. the stairs like arrangement formed can be seen here. The aim is to refine the visual senses of the child. He work with the cuboids as a set and form the pattern shown in the video. His control with own movements and impression about shape becomes refine. This activity helps in giving him a sense of heavy and light since the thinest cuboid is very light and the thickest one is very heavy for him to carry to the work area from the shelf.
