A manual contains 3000 examples on mathematics. Theme of "Ten" - one of the base themes studied in A-one. As well as any other, she requires an attentive comprehension and good fixing.As practice shows, a student mastered a theme fully, if decides an example and writes down an answer during 4-7 seconds. In this case it is possible to talk that skill of account is taken to automatism.Around to every page 7 columns are brought for 50 examples each. At the end of column the time spent by a student on a decision is written down. In the left lower corner control numbers mark: ideal time of decision of one column, satisfactory and result that must compel a student to be thoughtful.A teacher is difficult to check such plenty of examples, therefore better, if the time expended on the decision of every column will be marked by the adults of house.To attain good results, every day it is needed to decide on one page.A manual can be used as additional material on the lessons of mathematics, and also for work of house.
