(1) Strengthen oral arithmetic training to make practice make perfect for children.
Oral arithmetic is the basis of written arithmetic, the minimum basic skill that children should have, and a good means to train their thinking agility. Only by improving the ability of oral calculation can we improve the speed and accuracy of written calculation; Only by strengthening oral arithmetic training can we lay a solid foundation for operation. Insist on spending 3-5 minutes every day doing oral arithmetic training and memorizing some commonly used data.
(2) Through comparative training, let children develop serious habits.
Psychological research shows that it is boring to do the same job mechanically. Therefore, we can't improve the accuracy of children's calculations by simply strengthening the questions, because children often don't want to do it again after finishing it once. We should follow the teaching rules according to children's psychological characteristics and adopt different consolidation measures. Through comparative training, we can overcome the negative influence of children's thinking mode, let children develop the habit of careful examination and careful calculation, and cultivate their comparative discrimination ability.
(3) Cultivate the habit of careful calculation.
When learning arithmetic, we should cultivate children's calm and calm learning attitude. When you encounter a calculation problem with a large number and many steps, you should be calm, calm and patient. The calculation requires "look, think, count three times and check four times". At first glance, before doing the problem, you should read every number and every operation symbol completely and make a preliminary perception; The second way of thinking is to find out the relationship between the characteristics of data and operation on the basis of seeing the topic clearly, and choose a reasonable method according to the specific situation to determine the operation steps; The third calculation is to calculate carefully after determining the calculation steps and methods; These four inspections are to calculate each step in time; Look back. Check whether the method is reasonable and whether the calculation result of data operation is wrong.
