Math Challenge: Solving Stick and Square Puzzles
This article from Folha de S.Paulo presents a mathematical puzzle challenge titled 'Sticks and Squares 2,' developed in collaboration with the Institute of Pure and Applied Mathematics (IMPA) and the Brazilian Mathematical Olympiad for Public Schools (OBMEP). The core task involves manipulating toothpicks within a geometric figure to form specific numbers of squares under strict constraints. Initially, readers are asked to identify five squares in a standard grid. The main challenges require moving or swapping three to four toothpicks to create two or three squares, ensuring every stick remains part of at least one square's boundary. The article provides visual examples of invalid solutions, where unused sticks violate the rules, and reveals the correct configurations for each scenario. Adapted from Boris A. Kordensky’s 'The Moscow Puzzles,' this educational content aims to engage students and enthusiasts in logical reasoning and geometry. It serves as both an interactive brain teaser and a promotional piece for ongoing mathematical education initiatives in Brazil, directing readers to the OBMEP portal for further exercises.
