Proficiency in calculation and understanding of arithmetic are two main factors of calculation speed.

How to improve computing power? The trick is nothing more than two things, one is to practice repeatedly, and the other is to understand arithmetic. These two points are simple to say, but not easy to do.

The first is repeated practice. In this respect, I believe parents understand the importance, but repeated practice is a time-consuming and brain-consuming thing. It is not simply to let children do a lot of the same questions, but to make children interested and stick to it for a long time. This is to consider the diversity and interest of the problem.

Secondly, the understanding of arithmetic, which is often ignored, requires children to put more energy into understanding. For example, in the fourth grade, when learning the distribution law, there are a lot of exercises to use the distribution law to make clever calculations, such as

23 * 37 + 23 ? * 63 ? = ? 23 * (37 + 63) ? = ? 23 * 100 = 2300,

If we ask, what is the truth of the law of distribution? Why does multiplication have a distribution law? Why can you use the distribution law to do such a clever calculation? How many parents and children can answer accurately?

For another example, in the fifth grade, I learned the method of fractional multiplication and division, and 3/5 ÷ 2/3 = parents all know that dividing the score is equal to multiplying the reciprocal of the score.

3/5 ÷ 2/3 = ? 3/5 x？ 2/3 ? = 9/ 10

So everyone can work out the correct result. But if you ask again, why can dividing by a fraction be equal to multiplying the reciprocal of this fraction? Fractional multiplication Why is numerator multiplied by numerator and denominator multiplied by denominator? 90% of parents will be shocked directly.

Finally, bid farewell to blindly brushing questions, fun is the best way to learn.

In traditional arithmetic learning, most parents equate arithmetic with calculation, and only emphasize the mechanical practice of memory. If you can calculate, you can calculate correctly. However, this is all wet! We often say that mathematics cultivates children's thinking, so we ask: What kind of mathematical thinking have we cultivated by learning calculation in this mechanical way?
