Answer:
Cultural tools
Explanation:
Lev Vygotsky was a psychologist who developed a theory about cognitive development in kids.
One of the concepts of his theory is the "cultural tools" which refer to both technical tools and psychological tools that the kid uses in order to learn. The technical tools refer to physical things such as computers, books, toys, for example. On the other hand, the psychological tools are non physical tools such as language and numbers that are not tangible but that help in the process of learning.
Therefore, Vygotsky believed that actual physical items that a child uses to learn (pencils, books, computers, etc.) as well as the intellectual and conceptual framework that the child uses to learn (language, alphabet, number/math system) are called Cultural tools.
