DEVELOPMENT OF THE VECTOR-COORDINATE METHOD OF MATHEMATICAL MODELING
Abstract
In school, starting from the early grades, students are introduced to geometric shapes and solids. They solve problems involving the calculation of the volume and surface area of rectangular parallelepipeds and cubes.
In grades 5-6, mathematics textbooks introduce topics such as pyramids, tetrahedrons, prisms, and polygons. Studying these topics helps students develop spatial thinking.
Many students experience difficulties when studying polyhedrons: they struggle to name the number of faces and edges, calculate areas, or determine edge lengths. One solution to these problems is for students to create paper models using nets.
Paper models have the following disadvantages: they are not durable – they can be crumpled or torn; they are opaque – making it impossible to see inside the model; and creating many models requires time.
