KUMON. We learn to subtract. Simple tasks

KUMON is a method of individual development, which is used by 4 million children in 49 countries. Each book is a stepping stone to a certain skill and is designed for several lessons. The student independently performs game tasks, which are gradually becoming more complicated. Why will a child learn? The book will teach you to subtract numbers from 1 to 5 from integers within 20 and will help you understand this mathematical operation. All exercises in the book are built on the principle of "simple to complex": First, the child will repeat familiar topics: writing numbers and ordinal numbers. She will then be able to perform simple subtraction problems from 1 to 5. Then she will start subtracting these numbers within 20. It is very important that the future student thoroughly masters the principle of subtraction, because in the future, he will master more complex mathematical operations such as multiplication, division, work with fractions, etc. Thanks to the competent structure of KUMON manuals and the curiosity of the tasks, the child will be happy to master basic mathematical knowledge and seek to learn new ones. The book is printed on a special thick paper designed for children who are just learning to write. Such paper will not break, even if the child presses it with a pencil with all his might. In addition, it is easy to erase the drawn lines, so the child will be able to draw on the same pages many times.
