Pay attention to calculation
Computational learning of mathematics, like literacy learning of Chinese, is the most basic.
Illiteracy, poor Chinese reading ability; If you calculate badly, you can't learn math well. Moreover, good calculation will be of great help to children's math learning.
Parents can let their children do oral calculations for 2 minutes every day. At first, you can only complete 20 oral calculations in 2 minutes, but then you will find that children will be faster and faster, and the correct rate will be higher and higher.

Pay attention to mathematics in life
In fact, the study of mathematics has a great influence on life and can provide a lot of help.
For example:
Buy things, calculate interest rates, make profits, etc. , all in math. You can consciously ask your child math questions in your life and let him answer them. It's simple. You take your children to buy food, 5 yuan for a catty of apples, 20 yuan for your aunt, and change.
Don't underestimate these. In primary school mathematics learning, solving problems accounts for the most points, and solving problems is nothing more than judging which addition, subtraction, multiplication and division to use to solve them. These problems are actually problems in life. With more contact in life, children will naturally answer.

Activity preview
Before explaining new knowledge, it is an important means to read the teaching materials carefully and develop the habit of previewing actively. Therefore, cultivate self-study ability, learn to read books under the guidance of teachers, and preview with teachers' carefully designed thinking problems.
For example, if you teach yourself an example, you should find out what the example is about, what the conditions are, what you want, how to answer it in the book, why you answer it like this, whether there is a new solution and what the steps are.
Grasp these important problems, think with your head, go deep step by step, and learn to use existing knowledge to explore new knowledge independently.
Some parents have a headache and their children are inefficient in class; The key reason for this is that there is no preparation; Nature can't be targeted;

Thinking is the core of mathematics learning method.
Some children are familiar with formulas, properties, rules, etc. But when they encounter practical problems, they don't know how to start and how to apply what they have learned to solve them.
If there is such a problem for students to solve, "if the height of a cuboid is removed by 2 cm, it becomes a cube, and its surface area is reduced by 48 square centimeters." What is the volume of this cube? "
Although children are familiar with the formula for finding the volume, many students can't figure out the way to solve the problem because the problem involves a wide range of knowledge and requires students to gradually master the thinking method when solving the problem under the guidance of teachers and parents.
In terms of units, this problem involves length units and area units; Graphically speaking, it involves rectangles, squares, cuboids and cubes;
From the perspective of graphic change relationship: rectangle? Square; In thinking and reasoning: cuboid? Shrink a cuboid with a square bottom? Reduce the area of four sides to equal? Find the area of a surface? Find the length of a rectangle (that is, one side of a square)? The volume of the cube; Enlightened, after the child analyzes, students can answer according to their ideas (they can draw pictures).
Some students quickly replied:
Let the base length of the original cuboid be x, then 2X? 4=48
X=6 (that is, the side length of the cube),
So the volume of the cube is 6? 6? 6=2 16 (cubic centimeter).
Therefore, in the process of learning, the biggest role of teachers and parents is: inspiration.
Children, under the guidance of teachers and parents, actively think and solve problems and master learning methods!

Cultivate interest in reading
During the holiday, I talked to a senior teacher about children's math learning and shared a key point:
"How is your child's math?" The teacher asked.
"The problem is not difficult, and the results are not bad. When you encounter a problem, it seems that you can't get in. " I really have a headache when I mention my daughter's math.
"Does she usually like reading?" (This question may be as confusing to many parents as I am. Reading? Isn't that what Chinese teachers do? Use math. . . ? )
"I don't particularly like it, but I don't watch it at all. I usually like to read comics and the like. " I thought about it.
"Oh, have you read popular science books and some famous books?" The teacher then asked.
"No, I don't think she can see any books that are useful for learning, and she doesn't want to read them." I'm a little embarrassed to answer.
"There are some problems." The teacher paused and said, "If children want to learn math and physics well in middle schools in the future, primary schools must read more books, especially good books with profound humanistic qualities. Children who read more books have active thinking and broad horizons, and they can show their advantages in the senior grades. "
"Most of the students with good math scores can read books at the age of 6 or 7. In primary school, they read many good books with deep humanistic quality, and they love thinking and reading. The depth and breadth of these children's problems sometimes stumbles me.
Most children with poor grades are not interested in reading. The simplest difference between two children is that children who don't pay attention to reading ability often can't understand the meaning of the topic, or they are often unclear and careless when examining the topic.
In fact, the main problem lies in reading comprehension. No matter how teachers and parents help these children, their math scores will not be greatly improved. "
After listening to what she said, I understand better that "the more students read, the clearer their thinking and the more active their wisdom."
