“The Second Fabric Box 2 – White introduces oral activities while encouraging order, orientation, and therefore independence. The child achieves this objective by learning the names of the objects in the environment. Especially the names of things which sound or physically are similar.” (courtesy of Montessori Commons).
By touching, the child matches the fabrics according to textures. Because all the fabrics in the box are white, the Child needs to search their vocabulary to describe what they are feeling.
