The "Igralochka" workbook, Part 4 (2), is designed to develop mathematical concepts in children aged 6–7. It is part of the "Igralochka" set for children aged 3–7. The set also includes a curriculum, methodological guidelines for teachers with lesson plans for each session, demonstration materials, and handouts.

The "Igralochka" set is designed to develop preschoolers' thinking skills, creativity, and interest in mathematics. It is part of the "World of Discoveries" comprehensive preschool education program.

It is the first part of the "Learning to Learn" continuous mathematics course for children aged 3 to 15. It is directly followed by L. G. Peterson's mathematics textbooks for primary and secondary school.

The "Igralochka" set can be used in preschool education and for working individually with children.
