An out-of-print book, glowing with new colors, reappearing in the rivers and lakes! Mathematics masters are out, commanding the world, who competes! After 20 years of silence, it makes a stunning debut in a new style!
The children said: With it, bedtime stories can be replaced by it; parents say: With it, children fall in love with math problems; Chinese teachers say: With it, the kingdom of mathematics hides ancient poems; Mathematics teachers say: With it, the classroom form is more and more colorful.
What's so good about this out-of-print book?
Let's hear what everyone has to say!
The feedback has received rave reviews from children, parents, teachers, and people from all walks of life. One person saying good doesn't mean anything, everyone says good is really good!
If you don't know the details of this 20-year-old book, let me introduce you to this old and new "friend".
Let's start with the negative side, I have previously published a summary of some popular mathematics extracurricular books and popular mathematics books on the market, which commonly contain at least one of the following 4 giant pits with a wide range of complaints:
1. More than interesting, not enough knowledge
There are many comic-type mathematics science books, with vivid storylines and distinct characters, but the knowledge points and the story are basically the relationship between oil and water, and the integration is too poor.
I won't name this specifically, because I really can't click on it, basically this type of mathematics popular science book, everyone has seen or bought it.
2. More knowledge, not enough fun
This kind of book is a jump in knowledge points, and the difficulty is also jumping, and it is often out of children's acceptance, and at the same time, it lacks interest.
This kind of book has a certain storyline, and there are quite a lot or even too many knowledge points, and the two also have a certain degree of combination, but either the knowledge points are too jumpy, or there are too many symbolic calculations, too much difficulty, low interest, high reading threshold, too high persuasion rate, and too picky.
Some books are introduced to elementary school or junior high school students, and as a result, many of them are high school and college math knowledge points.
For the vast majority of primary or junior high school children who take the comprehensive route, there are a few who can withstand the new terms, formulas, abstract symbols, formal reasoning, high information density, high thinking density of math reading content stimulation.
It is a trivial matter to waste some money and put an extra set of books at home to accumulate dust, for fear that children will have misunderstandings about popular science books and have a great psychological shadow on popular science books in the future.
The role of popular science books is more to stimulate children's interest in the subject, and this set of books is more to use a large number of overly dense and jumpy terms, definitions, concepts, abstract symbols and formulas to stifle interest.
The reading of popular science books also needs to be gradual and step up. The book is too hard, and the abstract knowledge points are too difficult, and it is easy to lose your appetite.
Popular science books are not about the more knowledge points, the more difficult, and the deeper the better, but to have a knowledge point, interest and balance of the child's psychological stage.
3. The density of information and thinking is too low
This kind of book is actually quite interesting and knowledgeable, but it dilutes the knowledge points too much, and there are thirty or forty books in a set at every turn, and there is too much water.
A knowledge point of addition or rational numbers within 10 is a book, so the whole thing, after a school period, there are thirty or forty books.
Such a set of books is too low for the efficiency of children's reading and learning, and it is too low for the cost performance of parents' book spending.
In order to stimulate the interest of the subject in the enlightenment stage, it is enough to use one set, and if there are more types of such types, it is really not much necessary.
4. Shoddy work, low-level mistakes
This last pit is actually the most unbearable, which is also the direct result of the low threshold for publishing, the high market pressure in the publishing industry, and the eagerness for quick success.
Many non-professional publishers who make this book have launched production line types, fast food mathematics science books, and this kind of problem is prominent.
The author or editor or illustrator has too shallow mathematical skills, constantly copying, and there are many mistakes in the pasting of common sense knowledge points without knowing it, and the responsible editor of the publishing house does not have much sense of responsibility and professionalism.
After summarizing the negative side, I will state from the positive side what a good math extracurricular book and popular science book should look like.
Mathematics extracurricular books are an important and necessary supplement to in-class teaching materials and teaching, so the focus should be on stimulating children's interest in active reading and triggering children's rich divergent associations and convergent thinking through interesting and diverse forms and content rich in knowledge and thinking nutrition.
A perfect math extracurricular book should ideally contain:
Interesting and vivid history of mathematics, stories of mathematicians, mathematics in life, the expansion and deepening of textbook knowledge background, interesting and brain-burning thinking questions, through famous quotes related to mathematics, teaching mathematics learning methods, moisturizing things and silently conveying mathematical ideas and mathematical spirit.
Such a book will allow children to have both high-quality math reading input and relevant math puzzle output that will make them eager to try and interested.
With high-frequency, targeted thinking as the underlying link, input and output, perfect combination, stimulate children's fun and initiative in learning mathematics, and be able to read and gain, reading and doing problems with both hands, both hands can be hard!
This kind of math book can really make children feel that math is interesting, useful, and challenging.
This is also what a good math extracurricular book should look like!
After reading what I said above, do you think that Lao Wu is too idealistic, describing an unrealistic mansion in the air, and such a book only exists in the imagination?
It's normal to think like this, the math extracurricular books I have seen on the market before, there are indeed very few math popular science books that meet the above conditions at the same time, so you need to use multiple books, which will inevitably produce redundant combinations.
I also wrote an article to complain about this, and it was in that article that I revealed a set of extracurricular books that perfectly met all the above descriptions.
Because it is so rare, after nearly 20 years of being out of print and dusty, I am determined to promote the reprint, so that more children can benefit from it and truly feel the beauty of mathematics and the use of mathematics!
The outstanding merits of this book can be summarized in the following 4 points:
1. Authoritative and professional
This book is one of the most cited books for teachers to expand their knowledge, and I also found it in the teacher's book.
The editor himself has a good mathematical foundation, and in the process of editing, he also visited many famous schools, interviewed many front-line teachers rigorously and seriously, and invited experts to give professional comments and guidance on the book.
The special consultants for each book are a number of well-known special teachers and senior teaching researchers.
2. Balance between knowledge and interest
This book is a perfect combination of knowledge and fun, including the history of mathematics, interesting facts about mathematicians, mathematical games and thinking puzzles (classic and simple problems).
In the form of columns such as "Chinese and Foreign Mathematics Stories", "Mathematics in Life", "Interesting Questions", "Mathematics Game Palace", "Scientist Quotes", etc., and with the story, cartoon pictures are carefully drawn, which conveys knowledge to children vividly and interestingly, stimulates children's initiative in learning, guides children to practice and think, and helps children learn mathematics well.
This book is rich in content, containing more than 200 stories, more than 200 interesting problems and games, and is a very comprehensive mathematics learning material. When children read these interesting math materials, they unconsciously expand their math knowledge.
It can be used both as a classroom material for understanding the textbook and as a reading material for students outside of class. It is not only used for children's independent learning, but also as a teaching reference for teachers and practical materials for parents to guide their children.
3. Close integration with the class
Guided by the spirit of "New Curriculum Standards", this book combines the textbooks of the People's Education Edition, the Beijing Normal University Edition, and the Jiangsu Education Edition, covering most of the knowledge points of primary school mathematics learning. Refer to the order of the chapters in the textbook and arrange the content according to the modules.
4. Information and thinking density
Through the selection of content and the careful setting of columns, it is greatly ensured that the books contain appropriate information and thinking intensity, and the learning difficulty is always kept in the child's learning development zone.
A book of about 400 pages in primary school shows the rich and interesting content of mathematics itself in an easy-to-understand way from the development history of mathematics, mathematical celebrities, subject anecdotes, subject frontiers, mathematics interesting problems, mathematics games, etc.
At the same time, the content of the book column is carefully set. It not only helps students to improve their interest in learning and broaden their horizons, but also helps students understand the background knowledge and better understand the textbook, so as to learn mathematics well.
For example, in the primary school stage, regardless of the promotion of junior high school, make full use of the interesting thinking questions in this book, and there are not only selected good questions in the book, but also the answers to the analysis of ideas.
Without other textbooks, just by using this book well, children's thinking skills acquired through interest exploration and active exercise are basically enough to meet the needs of science learning in junior and senior high schools in the future.
This elementary school mathematics science book with onion mathematics, three tricks to pass, and 53 excellent papers, it is a very universal, quite perfect school mathematics advanced self-learning program.
This out-of-print reprint is not just a simple reprint of the original form.
In order to meet the current publishing requirements and the needs of parents, the paper size, material, font size, binding method, and correction of flaws in the content of the book have been optimized and adjusted.
According to the data and research results published so far, some outdated materials have been updated to keep the content up to date, and the math problems in the original book have been re-calculated and the answers have been checked, so that readers can better enjoy the fun of mathematics.
So this time, which is essentially out of print, has become a process that can only be followed by the publication of new books according to regulations.
After three months, after three reviews and three proofreadings by the teachers of the publishing house, it was re-published with a new book number, new binding, new cover, and new title.
Under the premise that the content of the theme remains basically unchanged, in order to better meet the needs of readers, the font has become larger, and it has become a large-character version of the small No. 4 Song style; the page has become larger, and it has become a 16-page large book; the binding is firmer, and the locking glue binding is adopted; because many group members are worried that this book is more than 400 pages, a bit thick, and that it may fall off after reading for a period of time, the publishing house has received the professional advice of the group friends conveyed by me, and has decided to use the "locking glue binding" binding method.
Glue binding refers to a binding method in which the pages are threaded together with thread, and then the pages of the printed matter are fixed to the spine with glue.
The advantage of sewing the book block is to glue the book block and add a thread to fix it, so that the content of the book can be fully displayed when the book is opened, and this binding method can effectively strengthen the firmness of the book.
