30,000 examples in mathematics grade 4

The manual contains 30,000 mathematical examples on topics studied in grade 4, including examples of division with the remainder. The original construction of the material allows us to ensure its deeper assimilation.
As practice shows, the student fully mastered the program if he decides an example and records the answer after 4-7 seconds. In this case, we can say that the account skill is brought to automatism.
On each page there are 5 columns of 47 examples. If the student solves the column in 5-7 minutes, this indicates a good level of preparation. He should go to the whole page no more than 35 minutes. To achieve excellent results, every day you should solve one page of examples.
The manual can be used in mathematics lessons, as well as for the work of the house
