The book contains diverse mathematics-related material, covering both historical topics and practical exercises. The introduction provides an overview of the book's content and objectives. The following chapters focus on famous mathematicians—Thales, Pythagoras, Euclid, Hypatia, and Archimedes—featuring presentations, posters, and exercises about them. A separate section is dedicated to the connections between mathematics and music, as well as geometric patterns, including tessellations, fractals, and various spirals (Pythagorean, Theodorus, and Golden Ratio spirals). The book also explores the relationship between mathematics and recycling and introduces tangram as a tool for developing geometric thinking. At the end of the book, there are teacher-created learning tasks and students' practical projects.
