Olympic math tasks. Grades 5-6. FSES

The manual presents non-standard mathematical tasks that can be used to prepare and conduct Olympiads with students in grades 5-6.
The first part of the manual proposes tasks that are conditionally collected by topics, the second part presents the tasks for tournaments, command championships, and correspondence Olympiads. An interesting approach to combining the solution of a non -standard mathematical problem with the capabilities of modern computer technology can be seen in the topic "Your friend is a computer", where there is also a solution in the Paskal programming language.
The manual is intended for teachers, organizers of the Olympiads, will be useful to students and all fans of mathematics.
