Mathematics with Self-Check. Problem Solving. Grade 3

Problems are the most important means of forming mathematical knowledge in elementary school students, one of the main forms of educational activity in the process of studying mathematics. The manual "Mathematics with Self-Check. Problem Solving" covers all types of problem-solving that a child will encounter in 3rd-grade textbooks, as well as a large number of non-standard problems and problems of increased difficulty. The book can be used both in individual homework with a child and in school during mathematics lessons, in club activities, or electives.
