The third grade belongs to the transitional stage. In primary school, mathematics is not difficult. And every textbook has infiltrated new knowledge in advance. For example, plane graphics, such as the first grade, are involved, but only limited to understanding simple plane graphics, such as triangles, circles, rectangles, squares, parallelograms and so on. The second grade requires students to further understand these plane figures, focusing on understanding angles and drawing angles, and understanding the differences between acute angles, right angles and obtuse angles. In the third grade, further, we should learn the perimeter of rectangles and squares. In the fourth and fifth grade, I was exposed to the area calculation of plane graphics. In short, primary school mathematics knowledge is gradually increasing the difficulty, infiltrating a little, and strengthening a little.

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.
