The article describes the development of an interactive lecture master class for teaching students a new strategy of presenting pictograms and diagrams when learning mathematics in primary school. This is the only form of providing students with accessible lecture courses using new methods of presenting topics to students. When explaining some topics when teaching mathematics for elementary school students, teachers can organize a good curriculum using pictograms and diagrams, and when teaching elementary school teachers, it is necessary to make a possible demonstration of new methodological aids for learning pictograms and diagrams. That's why we recommend the following master class. This gives an idea of the advantages and possibilities of the method of presenting pictograms and diagrams when teaching mathematics in elementary grades. Different models of using pictograms and diagrams in solving mathematical problems are proposed
