Principles of Problem Solving: Mathematics 2-1 (for 2026)
Description
Book Introduction
Build your confidence in math with "Moon, Hae, Gil"! Many parents complain, “My child is good at solving arithmetic problems, but I can’t solve word problems or descriptive problems.” or “I can’t do calculations because I don’t know what to find.” Why does this phenomenon occur? It's because children's reading comprehension skills, or the ability to read and understand text, are low. 『Moon·Hae·Gil』 develops mathematical reading comprehension skills through training in finding the desired solution and given conditions in a problem, and builds confidence in mathematical reading comprehension skills through problem analysis. When faced with a sentence or descriptive problem, you must first understand the problem analytically and then establish a solution strategy on how to solve it. "Moon, Hae, Gil" develops mathematical thinking skills and confidence in word problems by focusing on learning and applying eight problem-solving strategies. Why don't your math skills suddenly improve overnight? Have you ever been frustrated by the lack of dramatic improvement despite solving two or three workbooks? It's because you inevitably make mistakes when you encounter difficult problems, which prevents your scores from improving. 『Moon·Hae·Gil』 builds confidence in solving difficult problems by mastering the types of sentence problems. |
