3000 new examples in mathematics. 1 class. The score is within a dozen

The manual contains 3000 examples in mathematics. The theme of "dozen" is one of the basic topics studied in the first grade. Like any other, it requires careful comprehension and good consolidation.
As practice shows, the student fully mastered the topic if he decides an example and records the answer within 4–7 seconds. In this case, we can say that the account skill is brought to automatism.
On each page there are 7 columns of 50 examples each. At the end of the column, the time spent by the student on the decision is recorded. In the lower left corner, control numbers are indicated: the ideal time of solving one column, satisfactory and the result that should make the student think about.
It is difficult for the teacher to check such a large number of examples, so it is better if the time spent on the solution of each column will be celebrated by adults.
In order to achieve good results, every day you need to solve one page.
The manual can be used as additional material in mathematics lessons, as well as to work at home
