In a manual tasks are offered on a reiteration and fixing of material on all course of mathematics for 4 classes.A book is divided into three parts. Every part corresponds to one summer month and consists of five pages. It is 4 pages of practical tasks on every week and "theoretical" page with necessary rules. Verification work completes a book.If a child will spend for 15 minutes in a day on implementation of tasks, placed on a corresponding page, then he will repeat the passed material successfully, will develop the mathematical and logical thinking.Such work will bring an enormous benefit and during a school year. For example, in 4 classes in the first half of year it is possible to use a book "The Summer tasks on mathematics for a reiteration and fixing of educational material. 3 class", spending on exercises 5-7 minutes in a day and doing on the half of page. In the second the half of year can occupy on a book "The Summer tasks on mathematics for a reiteration and fixing of educational material. 4 class".Regularly calling to material of these books, a student will take ability to decide tasks, examples, inequalities to automatism, firmly will memorize mathematical rules that is included in the program of initial school.A manual can be used for collective and individual work in a class or at home.
