30000 examples in mathematics: 4th grade

The most effective way to learn to calculate quickly and accurately is systematic repetition. Tasks for each mathematical operation must be performed repeatedly to bring the skill of mental calculation to full automation. The student is offered to complete 30,000... tasks on the main topics of the 4th grade mathematics program. Having completed such a number of examples, the schoolboy will reliably consolidate the acquired knowledge. In the future, he will definitely be able to apply it when doing independent, testing, or simply homework. By regularly working with the trainer, the fourth grader: • will learn to calculate quickly and without errors; • will be able to assess his level of knowledge and achieve improvement; • will gain initial experience in evaluating the work done.
