3000 examples in mathematics. 3-4 grades. Mental arithmetic up to 1000. Non-table and table multiplication and division, addition, subtraction

The manual presents material aimed at developing mental arithmetic skills on basic topics of the mathematics course for 3-4 grades: table and non-table multiplication and division, addition and subtraction within 1000. Mental arithmetic develops students' quick thinking and attention, fosters mathematical ingenuity and strengthens memory. Proper organization of mental arithmetic classes in elementary school implies daily short exercises lasting from 5 to 10 minutes. Sequential execution of the manual's tasks will help students master mental arithmetic skills of all forms: Quick auditory arithmetic. The teacher orally states an example and receives the answer orally after a few seconds. Visual arithmetic. The examples are written down, and the answers are either stated orally or written by the students. Combined arithmetic. The teacher dictates examples, and the student writes down the answers. Oral problem-solving. Speed in arithmetic arises from prolonged training. However, the understanding of specific mental calculation techniques should come first, rather than the mechanical application of them. Mental arithmetic should precede, complement, or conclude the part of the lesson to which it is subordinate. The manual can be used in mathematics lessons as well as for independent work at home.
