The robot must collect all the "Data Crystals" without hitting a wall.

Misha placed a firm 'X' in the grid. In the world of informatics, an 'X' wasn't a failure—it was the elimination of a false possibility. Step 2: The Algorithmic Path

Misha looked at his grid. He had five names: Anya, Boris, Vera, Gena, and Dima. He also had five bicycle colors. "Gena’s bike is neither red nor blue."

Misha wasn't just doing homework; he was a "Logic Detective." Today’s case, assigned by Mr. Goriachev and Ms. Gorina, involved a missing bicycle and a group of five friends. Step 1: Building the Matrix

Finally, Misha reached the A secret message was hidden behind a substitution code where every letter was shifted three places forward in the alphabet. Logic Puzzles for 4th Grade - TPT

He wrote out the algorithm. If he missed one "Turn Left," the robot would crash into a bush. This wasn't just a puzzle; it was the foundation of programming. Step 3: Decoding the Message

This is a story about the world of for 4th graders, inspired by the workbook series by A.V. Goriachev and K.I. Gorina . The Secret Society of the Logic Grid

The school bell rang, but for Misha, the real game was just beginning. He didn't reach for a game controller or a smartphone; instead, he pulled out a slim, colorful workbook: Informatics in Games and Problems, 4th Grade .
