30000 examples in mathematics. 4th grade

The manual contains 30,000 mathematical examples on topics studied in the 4th grade, including examples of division with a remainder. The original construction of the material allows for deeper understanding. As practice shows, a student has fully mastered the program... if they solve an example and write down the answer within 4-7 seconds. In this case, it can be said that the counting skill has become automatic. Each page presents 5 columns of 47 examples each. If a student solves in 5-7 minutes, this indicates a good level of preparation. They should spend no more than 35 minutes on a whole page. To achieve excellent results, one should solve one page of examples every day. The manual can be used in mathematics lessons as well as for homework.
