First, pay attention to the cultivation of computing ability ideologically. As a teacher, we should actively cultivate students' good calculation habits, guide calculation methods and skills, design exquisite calculation problems, and cultivate students' calculation ability and interest. As students, we should take calculation as the content that we must practice every day. From oral calculation, vertical calculation, offline calculation, simple calculation and so on. Not much, but perfection. As long as you keep practicing, you can be perfect. A few months of persistence will definitely improve the computing power.
Second, pay attention to mathematical explanation. Calculation is the basis of learning mathematics well, and calculation is actually very simple. If you master the calculation method, the calculation problem will not be a problem. Every student in the class can do calculation problems. But why do some students calculate quickly and correctly, and some students make mistakes when calculating? There are many-contempt of court. We should not only be satisfied with knowing how to calculate, but also understand why we do it and make the arithmetic clear, which will help us to calculate correctly. For example: 0.52×0.4 Many students randomly calculate 20.8 or 2.08. There is a decimal error, and the correct result is 0.208. Why three decimal places? Students should be understood. 52 minus 100 is 0.52, and 4 minus 10 is 0.4. 52×4=208。 So 0.52×0. The product of 4 should be 208 minus 1000 times, which is 0.208. In other words, the product of two factors * * * should have several decimals. The reason is clear, and the natural decimal point can't be wrong.
Third, pay attention to the cultivation of computing habits. We often find that students with good calculation habits often make fewer mistakes. Some students are not excellent in their studies. But I don't lose points in the calculation. Because he has developed a good habit of calculating. Before you do it, you should read the questions accurately and make clear the order of operation. Find out the relationship between the numbers and do it. Some students have developed the habit of copying questions accurately. Some students often make mistakes when copying, and make very low-level mistakes. Have the habit of careful inspection. When you finish the calculation, you must learn to check, check the questions again, see if you copied them correctly, and then recalculate. Use multiplication test for division and addition test for subtraction to avoid mistakes.
