Cheerful Geometry. Workbook-Training

Mathematical start. Cheerful Geometry — a workbook that will help a child from 9 years old master the basics of geometry and learn spatial thinking.

The workbook is designed as a space journey. The child will take on the role of a star navigator and together with a guide alien Ray will set off to explore the distant corners of space.

Each chapter is a mission on a new planet: you need to plot a course between the star points, explore the Polygon Planet, build three-dimensional crystal-planets from unfoldings, decipher messages from the Delta-Gamma quadrant, and even repair a giant mechanism made of gears.

The plot is structured as a quest: to complete all the challenges, the child will need not only to solve problems but to think like a space traveler.
