This is an automatically translated description

The proposed manual contains 500 logical problems intended for use in mathematics and logic lessons in grades 1-4. Each problem is accompanied by a solution and an answer, which saves the teacher's time in class.

For the interest of younger students, the heroes of some tasks are fairy-tale characters. However, the content of many of the tasks in the manual is related to real life. Working on the tasks presented will help students develop logical thinking, memory, attention, observation, ingenuity, help to form the ability to quickly navigate and make decisions, and teach them to solve difficult life situations.

The tasks proposed in the collection correspond to the current mathematics programme for primary school.

Designed for teachers, methodologists, educators of after-school care, leaders of mathematical circles.
