Exploring Three Dimensions

In addition to using our sense of touch to determine texture and weight, our sense of touch can also provide information about size and shape. This is called the stereognostic sense.

Stereognostic Sense

Children enjoy the challenge of trying to guess what an object is by feeling it with their hands. Familiar objects can be placed in a bag so that children can reach in, feel one of several objects, and then try to guess what it is. They can then pull the object out of the bag and look at it to see if they were correct.

They also enjoy putting on a blindfold and trying to sort objects by holding them and trying to determine in which piles to place them. The picture on the left shows materials for such an activity.
