Oh my God, someone has finally summed up the quick calculation method of elementary school mathematics!
As a parent who cares about children's education, every time I see those boring math problems, I think: is there a way for children to understand quickly, and calculate quickly and accurately?Today, I finally found the answer!There is an article that summarizes the quick calculation method of elementary school mathematics, which is really practical!
First of all, we need to understand the basis of quick arithmetic - mental arithmetic. In mental arithmetic, children can quickly come up with answers by imagining and fiddling with abacus in their minds. This method is not only visualized, but also greatly improves the speed of calculation. For example, if you want to calculate 9+7, according to the abacus method, you can imagine 9 as 10-1, then 9+7 becomes 10-1+7. In this way, the children can calculate 7+3=10 first, and then come up with 10-1=9, and the answer is about to come out.
Next, there is the advanced technique of quick calculation - the distributive law. This technique is especially useful in addition and multiplication. For example, if we want to calculate 56+44, we can first split 56 into 50+6, and then split 44 into 40+4. In this way, you can calculate 50 + 40 = 90 first, then 6 + 4 = 10, and finally get 90 + 10 = 100. This method not only makes calculations simple, but also deepens the children's understanding of the distributive law of addition.
There is also a quick calculation trick - the splitting method. This trick is suitable for any problem that requires calculations. For example, if we want to calculate 23 12, we can split 12 into 3 4, so that we can calculate 23 3 = 69 first, and then 69 4 = 276. Alternatively, we can split 23 into 20+3, so that we can calculate 20 12=240 first, then 3 12=36, and finally 240+36=276. This method not only makes the calculations simple, but also makes the children more familiar with the various number combinations.
These quick calculations are not only easy to understand, but also very practical. As long as children master these methods, they can quickly come up with answers in a short time, which not only improves the speed of calculation, but also greatly improves the accuracy rate. Moreover, these methods can also stimulate children's interest and self-confidence in learning.
Parents, if you are as concerned about your children's learning as I am, you may wish to bookmark this article and study these quick calculation methods with your children!Believe me, as long as we work together, children will be able to go further and further on the road of math learning!
In conclusion, the quick calculation method of primary school mathematics is really important. By mastering these methods, children will not only be able to complete a variety of math problems quickly and accurately, but will also be able to improve their interest and self-confidence in learning. I hope that parents can pay attention to this issue and work together with their children to master these practical quick calculation methods!
