Cells and tables. Issue 26. Sirotovsky I.Ya.

The twenty -sixth book of the series “School Mathematical Mugs” is devoted to the tasks of cells and tables. Their complexity varies from very simple to the most difficult.

it includes the development of nine classes of a mathematical circle with detailed examples of various complexity, tasks for independent solution and methodological instructions for the teacher. All tasks are given with detailed solutions. Tasks related to the calculation of two ways of the same value, equations in integers, alternation and chess coloring, combination and divisibility, isolation of areas.

A significant part of the book occupy additional tasks with solutions and comments. For ease of use, the final part of the book, as always, is made in the form of handout.

The book is addressed to school teachers of mathematics and leaders of mathematical circles. We hope that she will be interesting to schoolchildren and their parents, students of pedagogical universities, as well as all fans of mathematics.
