Fascinating combinatorics for elementary school students. Issue 4

This book presents the tasks of combinatorics that contribute to the intellectual development of children and the formation of mental skills related to the choice of effective solutions, methods, actions, combinations of options in real life conditions. We are constantly faced with a particular problem, and here it is important to sort out all the options for getting out of a difficult situation, find the optimal solution to the problem and evaluate possible risks. One who is engaged in combinatorics and introduced to solving combinatorial problems will be able to cope with this.
All combinatorial tasks are proposed in four books (1-4 issues) The material is located as it is complicated. The answers are given to all tasks.
The book is addressed to parents of younger students, tutors, tutors, students of pedagogical universities and primary school teachers. All materials can be used in lessons, in the classroom of mathematical circles and various extracurricular activities
