Geometry for the 7th Grade, Ordinary and Not So Much. Part 1

The twenty-second book in the series 'School Mathematical Circles' is devoted to geometry classes for 7th grade students. It includes developments of eight classes of the mathematical circle with detailed examples of varying difficulty, problems for independent solution, and methodological guidelines for the teacher.
A significant portion of the book is devoted to a list of additional problems, their solutions, and comments. A list of the literature used is provided, as well as the authors of the problems. For convenience, the final part of the book, as always, is made in the form of handout materials.
The book is aimed at school mathematics teachers and leaders of mathematical circles. We hope it will be of interest to students and their parents, students of pedagogical universities, as well as all lovers of elementary geometry.
