Wang Baoqiang's mining legend
fast mental arithmetic is the only way to carry out simple calculation without any physical objects, neither abacus nor fingers, let alone chessboard and diagram.
the arrangement and difficulty of fast mental arithmetic textbooks are closely related to primary school mathematics syllabus and junior high school algebra, It's a quick calculation more convenient than primary school textbooks. Simplified the written calculation, strengthened the oral calculation. Simple, easy to learn, interesting, primary school students through a short period of training, a number of plus, minus, multiply, except, do not list the vertical, directly can write the answer<
the strange effect of quick mental arithmetic
all students above grade 3 have learned multiplication and subtraction of any number of digits.
in grade 2, the addition and subtraction of multiple digits, the multiplication of two digits and the division of one digit.
in grade 1, the addition and subtraction of multiple digits.
in kindergartens, large classes of children can learn multi digit addition and subtraction, multi digit carry addition, such as 5869 + 3516, multi digit abdication and subtraction, Such as 8185-6938, etc. It's tailor-made for preschool children to go through the primary school mental arithmetic ahead of time. It is helpful for children to learn fast mental arithmetic in kindergarten for them to go to primary school in the future.
children no longer use straw paper to do their homework, but write their answers directly by looking at the arithmetic.
fast mental arithmetic is different from "abacus mental arithmetic" and "hand brain arithmetic". Fast mental arithmetic invented by Xi'an teacher Niu Hongwei (teacher Niu Hongwei obtained the patent certificate issued by the State Intellectual Property Office of the people's Republic of China). Patent number; Zl2008301174275. Protected by the patent law of the people's Republic of China.), Mainly through certain rules in the teaching materials, the children are trained in fast operation of addition, subtraction, multiplication and division“ "Fast mental arithmetic" helps to improve the children's thinking and behavior of the order, logic and sensitivity, exercise children's eyes, hands, brain synchronous rapid response, calculation method and primary and secondary school mathematics has consistency, so it is very popular with parents of children
the teaching mode of fast mental arithmetic and primary school mathematics teaching materials is really synchronous:
1: be able to calculate by hand, the current ecation system in China is exam oriented ecation, and the standard of testing students is the test report card, so the main task of students is to take the exam, answer questions, and write questions by pen, and the training of written arithmetic is the main line of teaching. It is consistent with the primary school mathematics calculation method, and does not use any physical calculation, regardless of horizontal, vertical, even add and subtract can be used freely. Using pen to do calculation is a golden key to start the smart express
2: mingsuanli - Suanli puzzle. To be able to write questions with a pen, not only should the child know how to calculate, but also let the child understand how to calculate. Let the children understand the calculation principle in the puzzle and break through the calculation of number. Children do their calculations on the basis of understanding
3: Speed Training - it's not enough for speed training to be able to use written arithmetic. There should be a time limit for oral arithmetic in primary schools. It's necessary to use time to talk about whether to reach the standard, that is, it's not enough to be able to do arithmetic, and the main thing is to speed up
4: Enlighten wisdom - intelligence gymnastics, not only learning to calculate, but also focusing on cultivating children's mathematical thinking ability, fully stimulating the left and right brain potential and developing the whole brain. Through the training of fast mental arithmetic, preschool children can deeply understand the essence of Mathematics (including), the meaning of numbers (cardinal number, ordinal number, and including), the operation mechanism of numbers (the addition and subtraction of numbers with the same digit), the way of mathematical logic operation, so that children can master the method of processing complex information, divergent thinking, reverse thinking has been developed. The child gets a quick brain
I'm glad to answer for you. If you have any mistakes, please forgive me
Matters needing attention in the maze:
-
types of enemies
< / OL >
chaos (only 2 times), goblin, big goblin, spiritual aspirator, brain drinker, maulbol, yormgad, iron giant, utu, ancient qual, possessed snake, rocking Hongqiao monster< 2. It is difficult for the enemy to explain in detail
spiritual absorber and brain drinker: the weaknesses are guns, double swords, holy weapons and thunder magic
brain drinkers are the high-level version of spiritual aspirators, and their essence is the same. The trouble with this kind of weird thing is that its spray will directly rece the HP limit, so we must make quick decisions. Even though the prince will dodge, his teammates are not sure. p>
maulbol: his weaknesses are big sword, mechanical weapons, and fire magic
is the translation of Bank of China like the flower of the demon world? If you meet and throw a nuclear bomb, you can mend it with a big sword
yoolmgard: it can't be analyzed, but after experiments, the weakness is ray attribute magic. Its attack is fire attribute
like the boss of the sewer labyrinth near hammerhead shark, it has a higher level. Even with thunder pole, you can't get 99999 damage. You need 3-4 shots
Iron Giant: the weakness is big sword, shield and holy attribute weapons. The analysis result can't be seen, but ice attribute magic has effect
one or two are not difficult, but there will be four in the maze at the same time, and basically the whole team will rush into the street without freezing
uttu: the weak points are big sword, mechanical and holy weapons, which are immune to all three kinds of elemental magic. Its attack is mine attribute
the first kind of enemies appeared in the maze who are completely immune to magic. Fortunately, the blood is not particularly thick, and there are only two. When there is element resistance, it is not difficult to use a big sword to split
ancient qual: the weakness is straight sword and double sword weapons, immune to all three elemental magic. Its attack is mine attribute
will appear twice, the first time only one, the second time two, did not eat immune food, it is impossible to fight. The trouble with it is that it will run away to return blood by itself, and if the return blood is interrupted, it will put the instant death mine attribute magic, and the safety pin is not easy to use. Although it is not instant death, the whole team is pinched...
it can barely deal with one, but it's impossible to deal with two, because they are very mobile, even if you want to attack and kill one quickly, The other one will come to teach you how to be a man quickly. The blood is thick, and the magic sword can only fight half of the blood
in a word, don't try to fight without eating immune food, it's a waste of time... It can be said that other parts of the maze can fight without eating immune food, but it's impossible only here... Even if you eat immune food, don't be careless, its physical attack can also kill half of your blood
possessed Snake: the weakness is straight sword and double sword weapons. The analysis result can't be seen, but the thunder attribute magic has effect. Attack has petrification and frog effect, remember to change the parts
the high-level version of Naga in the plot. A hidden attribute is that it has a chance to explode when its hp is less than 1 / 3, which is a death attack. If you don't want to capsize at the end of the maze, don't get close to them when Lei Ji cools down. Be sure to finish with Lei Ji
rocking Hongqiao Monster: it can't be analyzed. Through experiments, its weaknesses are straight sword weapons and ice magic
in the evolutionary version of yoolmgad, even the vulnerability attribute has changed. It's not difficult to hit with ice. It'll take about 4-5 times to throw. Pay attention to dodge and don't hang up, or you'll have to hit at least 10 more layers
you can take a bus outside the station in Zhoukou. From Zhoushang road to the west of Ningluo expressway, the general fare is 40 or 35
