Mental arithmetic. Part 1. Quantitative account. For children 4-6 years old

A quantitative account is the first book of a series of textbooks on mental arithmetic. The series includes the following books: "quantitative account", "simple score", "composition of the number", "help of a brother, helping a friend", "combined account", "account at a mental level", "multiplication table".
The book is useful for teachers of preschool education, parents and children not related to mental arithmetic. Classes are built in such a way that children easily remember numbers, their pro-wing position and shape, they easily form a number of number. All these are the necessary conditions for the formation of the account.
The book will be appreciated by practitioners working in mental arithmetic and soroban programs. It can serve as a restless manual, and a wonderful addition to the materials already existing. The program is built step by step and aims to form the number of numbers and teach children visualization. The use of the manual greatly facilitates the accounting of the account at the mental level.
