3000 examples in mathematics. Extra -table multiplication and division. Different levels of complexity. 4th grade

The manual contains examples in mathematics for one of the basic for the 4th grade of topics-extra-table multiplication and division. Like any other topic, it requires attentive understanding and durable consolidation.
As practice shows, the student completely learned the topic if he decides an example and records the answer within 4 to 7 seconds. In this case, we can say that the account skill has been brought to automatism.
To develop the account skill to automatism, examples of different levels of complexity distributed through three blocks are proposed. The 1st level of complexity is 7 columns of ordinary examples, the 2nd level of complexity is 3 columns of the chains of examples, the 3rd level of complexity-2 columns of logical examples in which you need to correctly arrange signs. For logical examples at the end of the book, answers are given.
In order to achieve good results, it is necessary to solve one page of examples per day.
The manual can be used as additional material in mathematics lessons and for independent classes at home
