This article describes the use of the "powerful knowledge" concept in geography education in primary schools. First, the concept of powerful knowledge is briefly introduced in the context of building geographical thinking. Next, the authors describe four key geographical concepts: place, space, environment, and interconnection. The main part of the article describes the possibilities of applying these four key concepts to teaching. The authors further specify individual concepts using generalizations (big ideas). Teaching in this concept is not based on the mere memorization of partial geographical knowledge, but rather leads to the acquisition of key concepts whose meaning is universal, and these concepts can subsequently be applied in any geographical context.
