Our notebook contains exercises that will help your child learn to identify numbers as even or odd, learn about numerical sequences, master actions such as addition and subtraction, increase/decrease the number of objects using the number line; consolidate the concepts of "greater-less-equal"; remember how numbers are written and dialed on the abacus; learn to count on an abacus in three or more steps. The material consists of 10 lessons plus additional homework exercises. Theoretical material is at the beginning of the notebook with an explanation of how to perform the exercises correctly.A feature of our notebooks is the symbiosis of mental arithmetic and classical mathematics.Mental arithmetic is a UNIQUE method of teaching children that trains the speed of perception andprocessing of information and allows them to harmoniously develop both hemispheres ofthebrain at the same time by mentally visualizing the calculations on the abacus. A developed brain is the basis for successful future activities.The colorful notebook uses games as exercises, the main character of which is a curious rabbit Shoosha. The book will allow children to easily and naturally get acquainted with the design oftheabacus and the rules of moving the beads.From the first lessons the exercises train the ability to quickly state the previous and the next numbers to a given one, the ability to count from anywhere in the direct and reverse order, andtodetermine the place of a given number in a number series.Also, the workbook contains a lot of funny pictures and interesting tasks that create positive motivation for learning and actively develop the logic, memory, attention, and intelligence of children.We wish you and your child succeed in learning mathematics and mental arithmetic
