Don't believe me, listen to me-
First of all, the paper used for origami and the folding process present mathematical geometric figures, such as square, rectangle, diamond, triangle, trapezoid, circle, polygon and so on. Mathematical figures can be recognized during origami.
Secondly, in the process of origami, it is a process of knowing numbers and learning to count. A few sheets of paper, folded several times, have several edges, several diamonds, several vertices, several corners, etc. Count as many as you can.
Moreover, origami is a hands-on operation process to cultivate a sense of spatial orientation. When learning mathematics, we will learn coordinates, so we need to know the words in the direction of up, down, left, right, front and back. When children fold paper, we can tell them to fold up, turn down, press to the right and so on. With a sense of spatial orientation, it must be helpful for mathematics learning.
Also, in the process of origami, you can compare and learn symmetry.
Such a powerful origami function, what kind of works should be folded to maximize these functions? Recently, I found an origami book to cultivate mathematics easily, which was written specifically from the aspect of cultivating children's sense of mathematics. Cultivate children's mathematical ability in origami games.
Look at the table of contents of this book, which is arranged according to the corresponding mathematical knowledge.
Chapter 1 starts with a triangle, with triangular boats, triangular butterflies, triangular wizard hats, triangular Mount Fuji and so on.
The second chapter starts with rectangles, and all the folded works contain rectangles or squares, including cars, buses and small houses.
The third chapter begins with symmetrical shapes, including babies, small fish with mouths, pans, jumping rabbits and so on.
Chapter 4 starts with the same shape. There are at least two identical shapes in a work, or they are also symmetrical to each other. Such as mushrooms, shirts and so on.
In chapter 5, back to the "triangle set", many triangles will appear on an origami. Let's count how many triangles will be folded in the process of origami and what shapes will appear when the triangles are put together.
The sixth chapter is the combination of two origami works. This is a masterpiece suitable for children aged 3-5, but the book is easy first, then difficult, and gradually easy from difficult to difficult. In this process, the children have laid the foundation of origami, and then it is not so difficult to finish the final great work. Confidence will certainly not be affected.
My children and I selected a few books from this origami book to cultivate a sense of mathematics easily and fold them first. Tulips are relatively simple (difficulty coefficient 1 star). Just fold a square piece of paper into a triangle, then fold the two bottom corners of the isosceles triangle upwards to complete the flower part of the tulip, then stick it on another piece of paper, and then draw the stems and leaves, and it becomes a complete tulip. If you change the folding method of tulips a little, then point your eyes and draw your nose and mouth, you can become a puppy. Well done!
Then I chose a small house with a difficulty coefficient of two stars, and later I directly upgraded it to a crayon, rocket and small box with a difficulty coefficient of three stars. This book is mainly aimed at children aged 3-5, and the difficulty coefficient marked in the book is also aimed at children of this age group. This is the standard of quantification. If nothing else, just counting a few stars and coloring them in bright colors is also part of counting.
In the description of the steps of origami, each step is also marked with "1, 2, 3 ..." In order to, on the one hand, let children of this age know numbers and learn mathematics; On the other hand, let children know the sequence of steps and cultivate the habit of doing things in an orderly way.
There are finished drawings, clear hand-drawn steps, corresponding mathematical knowledge and other extended origami games in the book. Lovely origami works also conform to the age characteristics of children, and are relatively easy to learn and fold.
In the whole process, mom and dad can accompany their children to make these origami works, or they can show them first, teach their children the basic essentials of origami first, and then encourage them to operate by themselves. Before starting origami, this book provides the basic knowledge of origami. Every origami work has detailed graphic steps, and of course there is a lot of mathematical knowledge in the corresponding origami. The combination of the two can enlighten children's multiple abilities.
1. origami helps children learn to think and cultivate their hands-on ability.
Children need to learn and think about folding methods in the process of origami, and they must be able to exercise the coordination of their hands and improve their hands-on operation ability.
2. Cultivate children's observation and imagination.
In the process of origami, children need to combine their own observations, develop the habit of doing things in an orderly way, and guide children to imagine.
3. Improve children's aesthetics
Origami has a strong plasticity, and a piece of paper can be ever-changing, and the folded works are exquisite and beautiful, which is aesthetic education and enhances children's artistic aesthetic ability.
By putting abstract fractions, geometric figures, etc. It is easier for us to understand when we turn into image origami, and our spatial imagination ability is also improved in the process of folding again and again.
4. Cultivate logical thinking and mathematical consciousness.
The folding of paper in origami is a changing process of mathematical geometry, as well as mathematical knowledge such as proportion, equal division, abstract fraction concept and graphic symmetry. Those seemingly abstruse mathematical knowledge become concrete and vivid.
All this knowledge is covered in the origami creation of the book "The Book of Easily Cultivating Mathematical Sense". In addition, the small knowledge points of origami also include common sense of life and Japanese holiday customs. (Because this book was imported from Japan), and the author of this book is Heyuko, a technician of the Japanese Origami Association, and Jing Daole Chiqiu, a Japanese infant arithmetic lecturer. Both of them are very professional and experienced in both theoretical knowledge and practical operation.
We don't need to elaborate on the more benefits of origami. Fathers who origami with their children have a deep understanding. In addition to the above advantages, origami can also promote communication between parents and children. In the process of origami, children develop their expressive ability through language communication with their parents, teachers and friends. When the origami works are completed, even when every step of the origami process is completed, the children's self-confidence will be involuntarily enhanced, and they will have a sense of accomplishment when they see their finished products.
