Perfect for sudoku fans—the rules for these 100 logic puzzles are simple, and the math is easy. But the puzzles get harder and harder! Once you match wits with area mazes, you’ll be hooked! Your quest is to navigate a network of rectangles to find a missing value.Just = length × widthUse spatial reasoning to find helpful relationshipsWhole numbers are all you need. You can always get the answer without using fractions! Originally invented for gifted students, area mazes (menseki meiro), have taken all of Japan by storm. Are you a sudoku fanatic? Do you play brain games to stay sharp? Did you love geometry . . . or would you like to finally show it who’s boss? Feed your brain some area mazes—they could be just what you’re craving!
I have just completed the last of the 100 puzzles in “The Original Area Mazes”. I enjoyed these puzzles more than any book of puzzles I’d ever before encountered. The puzzle difficulty goes from one-star all the way to five-star (more difficult) puzzles. Solutions (including explanations for the solutions) are given for all puzzles. I always solved the puzzles by using my own strategies – sometimes being less proficient strategies than what I found in the book’s solutions. These puzzles encourage a great deal of creativity.
Having a good sense of geometry is very helpful. Even though I’m tolerably competent in mathematics, I do not perform all so well in geometry. Some of the puzzles in this book were really tough for me. Nevertheless, by working a few puzzles on most days since I received the book, I solved the 100 puzzles in about 42 days. Most of the puzzles up to 4-or-5-stars were fairly easy. I often used some elementary (high school) algebra in order to solve certain puzzles, but pure geometrical manipulation and insight are simply indispensable for some of the puzzles.
I highly recommend this book for any puzzle lovers. I’ve done lots of Sudoku puzzles, but these puzzles were more interesting and more logically taxing than Sudoku is. These puzzles DEMAND logical thinking.
کتاب معماهای چارگوش ۱: ۱۰۰ معمای جذاب با ریاضیات ساده و منطق هوشمندانه (ویراست دوم)
بخش اول کتاب به معرفی قوانین حل این معماها میپردازد. سپس معماها را در پنج سطح دشواری متفاوت – از بسیار ساده تا بسیار چالشبرانگیز – خواهید یافت و در بخش انتهای کتاب نیز حل تشریحی تمام معماها قرار دارد.
فراتر از محاسبات به این معماها نگاه کنید. نگرشی منطقی و کُلنگر داشته باشید. یافتن پاسخ بدون اینکه درگیر محاسبات پیچیده ریاضی شوید از خصوصیات بارز «معماهای چارگوش» است. اگرچه محدودیت سنی برای استفاده از این کتاب وجود ندارد و برای همه عاشقان معماهای ریاضی، قابل استفاده است اما به طور اخص این کتاب برای دوره دوم ابتدایی و دوره اول دبیرستان توصیه میشود.
تمامی معماهای این کتاب با دانستن تعریف «مساحت مستطیل» قابل انجام هستند و در هیچ کدام از معماهای مربوطه، نیازی به حل معادله یا استفاده از محاسبات پیچیده نیست. این کتاب تألیف طراح مشهور ژاپنی، نائوکی اینابا است. تمامی معماهای این کتاب با ریاضیات ساده و منطق صرف، قابل انجام هستند. معماهای چارگوش به طور ویژه به تقویت هوش ریاضی و منطقی مخاطب میپردازد و در عین حال تمرینی بسیار موثر برای پرورش خلاقیت و کسب مهارتهای حل مسئله است. این معماها در حال حاضر به شکل گستردهای در سرتاسر جهان برای مقاصد آموزشی، مورد استفاده قرار میگیرند.
These were so fun! As a math person it took some getting used to - to focus ONLY on logic and the most basic principle of area equals width times height, and only using whole numbers. I really appreciated the gradual increase in difficulty for this reason, as it frequently built on strategies learned in earlier puzzles. I also appreciated the thorough explanations of each solution - sometimes I used a different strategy to come to the correct conclusion, but most of the time theirs was much more efficient ;-)
