The 5th grade Elementary students, in Unit 6, worked on the concepts of organization, logistics, structure and linkage that were integrated into our central idea “Every organism has defined processes and logistics that are linked together”. These concepts and central idea were put into action through the students´ projects for the 2024 Business Fair. During this event it was possible to visit the stands where the students exhibited various business models for different types of companies that were based on their knowledge and interests. It also put into practice their knowledge from the areas of natural and social sciences, English and mathematics with a transdiciplinary approach.
