Гигантская энциклопедия школьника

This new type of encyclopedia — with developmental tasks — will be a faithful companion throughout several years of school life. It contains and systematizes extensive reference material about plants, animals, humans, space, science, and technology. The second part of the encyclopedia, which includes about 1000 questions and their answers, will help the student learn even more new things, consolidate acquired knowledge, and develop their analytical skills and intuition.
