3000 examples in mathematics. Interesting tasks and challenging problems. With answers and explanations. For grades 3-4.

The manual contains tasks on all topics of the mathematics course for 3-4 grades. It includes non-standard tasks that expand the basic knowledge system of first graders. The material of the manual will help students consolidate what they have learned, train their memory, develop logical thinking, and improve their ability to find correct solutions to complex problems. When performing non-standard tasks, students practice establishing cause-and-effect relationships, constructing problem-solving methods, demonstrating not just additional knowledge, but the level of their independence. The difficulty level of all tasks is higher than basic, which is why they will be a good training for those who want to participate in school mathematics olympiads. The manual will also help teachers occupy students who complete all types of tasks faster than others in the class. For convenience, at the end of the book, there are answers and explanations to tasks that may cause difficulties. The manual can be used in school lessons and for independent study at home.
