Can perform seriation task

Explanation:

The seriation concept was proposed by Jean Piaget in his cognitive development theory. These concepts explain the ability to group objects such as height, weight, length and the importance of the objects.

There is an instance of seriation such as children put objects from short to tall, small to long and then the importance of an object.

Seriation is a phenomenon that deals with size, weight, and magnitude. This concept helps children in learning their math and science concepts.
