Brown Stairs
Seeing thickness, one step at a time
The Brown Stairs help children notice how objects change in width. Each prism is the same length, so the focus stays on one clear difference. As children compare, carry, and arrange the prisms, they strengthen their eye for detail and build early mathematical thinking.
Pink Tower and Brown Stairs
Both materials teach size, but in different ways.
With the Pink Tower, children explore cubes that grow in every direction. They see height, weight, and volume changing together.
With the Brown Stairs, only the thickness changes. This helps children study one dimension at a time.
Placed side by side, the differences become clear. One shows “taller,” the other shows “thicker,” and children begin to understand that size has many forms.
