Maths. Grade 2. Textbook. In 3 parts. Part 3

The textbook is the result of a generalization of many years of work of the author with children of 5-9 years in mathematics lessons. In addition to the classical direction of studying mathematics - the formation of computational skills and acquaintance with the simplest geometric concepts and algorithms - in the book, great attention is paid to the combinatorics and theory of graphs (which, in fact, is rare for books intended for younger students), as well as the development of logical thinking, non -standard Look at the world. In most lessons, the first half of the material corresponds to the general educational program of primary school in mathematics, while the second part of the lesson is unique for educational books of this kind and contains many tasks for the development of intelligence.
