First of all, we should cultivate children's concentration. Secondly, let the children read the questions repeatedly. Don't worry. First, we should understand what the conditions given in the title mean and what are required. If you don't understand the meaning, blindly doing the problem can only be a mistake. Therefore, reading and reviewing questions are the key, but it is more important to cultivate children's understanding ability. This aspect needs bit by bit and long-term practice. Parents can't worry, they can't do it for them, especially they can't help their children see the problems. If they do this, they will only make children form the habit of dependence and are unwilling to find ways to overcome the difficulties in math learning!
Finally, parents should be patient, spend more time with their children, and do brainstorming puzzles with their children to improve their interest in learning mathematics. This is the most crucial point.
