A big book of examples and tasks on all topics of the elementary school. Grades 1-4. Mathematics. Super -training

Here is a unique manual for teaching schoolchildren to the skills of an oral account. It combines examples and tasks on all topics of mathematics for elementary school. The manual consists of 56 sections, each of which is devoted to a separate topic. The section consists of three parts:
- examples for working out speeding skills. The page shows 5 columns of 35 examples in 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. 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 is brought to automatism. - Logical examples. The implementation of these tasks develops logical and mathematical thinking, memory and attention. At the discretion of the teacher, examples can be used both for olympiad and tasks of increased complexity, and for repeating and consolidating the topic. Control and verification work. With their help, the teacher will be able to quickly evaluate the skills of calculations received by students and identify "weak" places. The manual can be used as additional material in mathematics lessons, as well as for homework
