One Friday, the teacher announced a "Joint Math Quest." Students from both classes had to work together.

In Sasha’s school, the 3rd grade was split into two camps. In Classroom A, they followed the path of . In Classroom B, they ventured into the world of Lyudmila Peterson . 1. The Garden of Moro

To Sasha, Moro’s world was safe. If he followed the rules, the answers always appeared. But sometimes, when the homework got tricky, he reached for his —his secret map. It wasn't just about copying; it was about seeing the logic behind the "long division" dragon he had to slay that week. 2. The Labyrinth of Peterson

A complex riddle involving a train (Moro's specialty) that traveled through a Venn diagram of three different cities (Peterson's territory).

Together, they realized that math wasn't just one book or one author. It was a language. Sasha’s precision and Misha’s abstract thinking were two sides of the same coin. They solved the riddle before anyone else.
