Skillofun Broad Staircase

There are ten brown, wooden prisms all the same length but varying height and width from 1 centimeter to 10 centimeters (or one decimeter squared)
This is designed to teach the concepts of thick and thin
Each stair is 20 centimeter in length and varies in thickness from 1 to 10 centimeter
When put together from thickest to thinnest, they make an even staircase
As an extension, the broad stairs are often used with the Pink Tower
