Аннотация:The article outlines the problem of using the potential of toy books in preparing bachelor students for purposeful work on the formation of mathematical concepts in preschool children and suggests the idea of organizing the creative activity of students to design toy books with mathematical content.The article contains an overview of classifications of toy books, pedagogically characterized and methodically described examples-constructs of various types of toy books created by bachelor students. The pedagogical potential of these constructs allows us in this work to consider a toy book as a means of mathematical education for preschool children.The conducted research and analysis of the results allowed us to obtain data on the importance of including in the process of training future teachers-educators a creative technique - the design of toy books with mathematical content.
