Keep doing oral arithmetic exercises every day. Some children are unwilling to do oral arithmetic exercises, and their oral arithmetic ability has never improved. Not only slow, but also easy to make mistakes. If the child's calculation is always wrong because of lack of oral expression ability, then parents should urge their children to do some oral exercises every day, not only to care about the accuracy of oral exercises, but also to do oral exercises within the specified time, and to think after each training, sum up the main reasons for doing a wrong set of questions, and then do some similar questions to consolidate and prevent repeated mistakes.
Some children don't want to use column vertical method to calculate the file format of standard column calculation, but their oral calculation ability is not good and they make mistakes in calculation; Some children usually like to use calculators to calculate, whether orally or in writing, they will lose a lot of points in math tests. If the child's written calculation ability is insufficient, parents should urge the child to use less or not to use calculators. In the case of poor oral calculation ability, it is best to use the column-vertical method for calculation. At the same time, parents should also urge their children to write every step of the calculation steps on grass paper. As long as children keep practicing and form a good habit of standardized writing, they can steadily improve the processing speed and accuracy.
Summary and simple calculation methods Some children will not use simple calculation methods to calculate, which will lead to very low processing speed and accuracy. If children are not familiar with simple calculation methods, parents should urge their children to write down the formula calculation of additive commutative law, additive associative law, multiplicative commutative law, multiplicative associative law and multiplicative distributive law in conspicuous places. Every time they brush the questions, they need to look at this algorithm again and again until they use it flexibly. Naturally, in addition to clearly stipulating that the calculation rules must be applied to problems calculated by simple calculation methods, parents also need to remind their children to master these calculation rules in all mathematical calculation problems, which can obviously improve their calculation ability.
