Efficiency formula of primary school mathematics homework
The formula of primary school mathematics work efficiency: work efficiency = total amount of work ÷ working time.

Work efficiency generally refers to the ratio of work production results to input, which is used to express the level of work production efficiency and how much work a person has completed in unit time.

There are several ways to improve personal work efficiency:

1, keep the best work passion. Enthusiasm for work can also be said to be willingness to work, that is, whether you want to do it, whether you want to do it well and quickly, whether you are active, serious and responsible, and whether you are perfunctory and procrastinating.

2. Choose the right working direction. The work direction is the work goal or purpose.

3. Choose the best working method. There are various ways to do any work, and maybe all of them can achieve the same goal through different ways. Just like solving a math problem, there are many ways. Since you can get the answer, what method would you choose? Nature is the easiest. In this way, we can have more time to solve other difficult problems and ensure the quality of the test paper.

Similarly, finding the best method can save us unnecessary time waste. So before you start work, please think carefully about what is the best way. That's what the woodcutter said.

4. Selection and use of tools. "If a worker wants to do a good job, he must sharpen his tools first." Choosing a good tool can get twice the result with half the effort. The use of tools requires us to pretend to understand with an open mind and consult others with an open mind. As you know, you can't ignore your colleagues' suggestions because of your own selfish interests. After all, every job can't be completed by one's own ability. Work is a collective project, and pleasant cooperation can improve efficiency.

5. Know how to combine work and rest. Whether studying or working, the combination of work and rest is very important, which can make people get twice the result with half the effort. If you overwork, it will not only affect your health, but also reduce your work efficiency. Working long hours is to finish the work better, but it backfires. Isn't it "losing your wife and losing your soldiers"?
