Principles of Problem Solving: Mathematics 2-2 (for 2026)
Description
Book Introduction
Confidence in math that grows with literacy and wisdom!

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.


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? Are you frustrated because you're solving two or three workbooks at a time but your math skills aren't improving dramatically? 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.
