Sudoku has appeared on the stage of super brain many times. This time, it is actually the Mobius ring that joins hands with it. What kind of sparks will their cooperation spark?
Mobius ring is a very strange ring. The method is simple. Take a piece of paper, rotate one end of the paper by 180 degrees, and connect it with the other end of the paper with adhesive tape. In layman's terms, it is to connect the two ends of the paper together, but you need to screw up the paper. This ring was discovered by mathematician Mobius, hence its name.
What are the characteristics of this ring? You can take a pen and draw a line on this paper made of Mobius ring. If you keep drawing, you will find that both sides of the paper are drawn with lines. It can also be said that the length of this paper has doubled.
If you take a pair of scissors and cut it from the middle of the paper, you may think that you can get two rings, but in fact you get a big ring twice as long. This big ring is neither a flat paper ring nor a Mobius ring, but it is twisted again.
If you take a pair of scissors and cut from the third part of the note, what will you get? Finally, you will get a big ring with small rings. This is really interesting. Maybe what you think with your brain is different from reality, so you must try. Baba Ma Bao can do magic tricks for babies.
After talking about Mobius ring, what is Sudoku? Sudoku is actually a board game in which nine small nine squares are recombined into a 9×9 square in the form of nine squares, and the number 1-9 can only appear once in each row, column and square. In our usual Sudoku game, some numbers are known. Fill in 1-9 in the blank box to meet the above requirements.
The Mobius Sudoku ring in the super brain is made of a piece of paper, with five Sudokus written on both sides of the paper, and then cut in a third of the paper, where a small palace ends, so that a big ring is covered with a small ring.
The super brain's way of playing is to separate this set of Sudoku rings. Make 50 rings that look the same at the same time, but in fact the numbers on these rings are not really Sudoku, and these are all interference items. Then replace two of the 100 rings with a set of Sudoku rings, and the player needs to find out these two Sudoku rings.
How do we play?
It's not troublesome to make a Mobius Sudoku circle, but it's troublesome to make 50 distractions, so you can't play this game directly and need to improve it. We can make 3-5 Mobius Sudoku collars and cut them out to find a match. You can also do only one set and do a few more small loop interference items to find a unique match.
The key is how to make this Mobius Sudoku ring. Actually, it's easy to do. Let's do it together!
The first step is to find a piece of paper and draw five Sudokus on both sides of the paper. It is suggested to use A4 square paper. The square can be directly used as a small square of Sudoku, and only one side of five big nine palaces can be drawn.
Step two, find a ready-made Sudoku. If you have a Sudoku book at home, I believe there is an answer at the back. Just copy it and it's OK. If not, search online, just need the answer. Of course, if you want to do it yourself or play slowly with your children, you can find some Sudoku questions and fill in the answers slowly. Fill in 10 Sudoku on both sides.
Step 3: Cut off both sides and stick them with transparent glue. Of course, you can also cut off the squares after drawing them in the first step. Transparent adhesive is used to enhance the strength of Sudoku. It's just paper, twisted and cut, which may be almost useless when playing.
Step four, let Mobius ring. Twist one end of Sudoku stick and connect the other end with adhesive tape.
Step 5, cut along 1/3, which is the end of a small palace, and get a set of large and small rings-this is the Mobius ring we are going to make.
I want to recommend this game mainly because:
Children like it.
This production process alone will attract children, and every step in the middle can be completed independently by primary school students. Sudoku is a very popular game, you can play it as long as you can count, and the Mobius ring itself is full of magic. But if Sudoku is just copied in the production process, it may be boring, but if it is done one by one, it may take a lot of time. Therefore, in the production process, we can combine the actual situation, copy a part to do a part, do a part by ourselves, and do a part by children.
The action of "cutting" is recommended for children because it is a magical process from one ring to two rings. And only by doing it yourself can we know where the corresponding position in the Sudoku ring has gone. For example, this small ring is actually the middle part of Sudoku, while the big ring is both sides of Sudoku.
The improved matching game reduces the interference. As long as children master certain tricks, such as finding the position of transparent glue for connection to determine the first line of Sudoku, it is still easy to succeed, so children will be very interested while experiencing the happiness of completing one thing.
Exercise observation and logical thinking.
To test the accuracy of Sudoku, if not, it depends mainly on observation. In the production process, if Sudoku is done by oneself, then the observation and logical thinking ability will be examined more.
