3000 examples in mathematics. Super training. Chain of examples. Three levels of complexity. 1 class. Uzorova O.V., Nefedova E.A.

“The manual will help to form an account skills on basic topics of the first class:“ The account is in the range of 5 ”,“ The account within 10 ”,“ The score is in the range of 20 ”. How to understand whether the skill of account is brought to automatism? For each sign of action, 3 - 4 s is assigned. If the child considers it good, then an example is 8-2+3-4+3-6+2+1 = he will solve for 20-25 s, a good result will be 30 s.

Tasks of three are given complexity levels: 1st level of complexity - calculate the answer; 2nd level - solve examples for a while, under the columns the time is indicated to solve all examples of this level: - excellent result, - good, - it is worth training more; 3rd level - insert the number missed in the example.

Solution of the chain of examples is an effective training that allows you to bring to automatism the computing skills of the child. Automated account skill will help save precious time when solving problems, long examples, inequalities and equations. In addition, an automated account will develop memory, logical thinking, flexibility of the mind and quick wit in the child, as well as significantly increase the brain performance - activates the development of speech and intelligence, the ability to retain and switch attention.

The manual will be useful for working in class and independent classes at home "
