15,000 Examples in Mathematics. Mental Arithmetic. All Types. Grades 1-4

All calculation methods and all types of tasks for automated counting skills:
• The manual includes tasks that allow for deeper comprehension of the material: mathematical dictations containing all possible formulations of tasks; chains of examples (calculations considering the order of... operations); column chains (calculations that proceed sequentially from top to bottom); calculations based on diagrams (determining the sequence of calculations, filling in empty cells of the diagrams). By completing the tasks, the student practices establishing cause-and-effect relationships, choosing methods of solution, develops mathematical intuition and logic, and masters counting skills to the level of automation.
For self-checking, tests are provided. At the end of the book, answers to column chains, tests, and diagrams are included.
