From the publisher:
The proposed material will help in an accessible, playful way to acquaint the child with the basics of mathematics, the concepts of "one-many", "more-less", "as much", some plane and three-dimensional figures. The main focus is on numbers and figures, their quantitative and ordinal values, working with mathematical signs, solving examples and problems.
The convenient small format makes it possible to take the book with you on the road or on holiday, to study with it while walking.
