Our class has just finished learning this unit, and it is also a headache for teachers and students, students do not understand enough to solve the problem of the application problem, especially the application problem of finding the amount of the unit "1", the student does not have a little thinking space, like the basic method of the example problem The student basically grasps it, but the fraction method is not easy to master, because the student's thinking space is not opened, there is a certain difficulty in finding the corresponding fraction, so we should strengthen the training of finding the amount of the unit "1" and the corresponding fraction in teaching, so as to open the door of students' thinking. And in the classroom to strengthen the ability of students to speak mathematics, in teaching, I found that students do not like to speak in class, there is no classroom atmosphere, let alone active, I began to observe the life of students, and later found that students are not because they can't, but afraid of saying wrong, I deliberately said a wrong question in class, to see if the student can point it out, and as a result, a student pointed it out, I said that the teacher will make a mistake? If you make a mistake, correct it in time, it's nothing! It's okay if you make a mistake in class, but through the teacher's timely explanation, isn't it correct again?
So we have to share our thoughts with the teacher in class! It's not a problem to say something wrong! Your classmates and teachers will help you correct it!
Isn't that great? I hope you can do that!
Now there are many students in the classroom who dare to raise their hands to speak, so that they can mobilize students' enthusiasm for learning, and students will slowly like to speak, so that they will form a problem with multiple solutions, and it is the students themselves who take the initiative to come up with it, which is more conducive to opening up students' thinking space, and in the long run, will you still worry about students' grades not improving?
I also think that speaking mathematics can also improve students' language organization and communication skills, many students who don't like to talk have begun to learn to communicate with others, and will also communicate with teachers and classmates about their inner things, students also gradually like math class, and also like me as a math teacher, I am happy from the bottom of my heart! I believe that I will lead the students in our class, I am confident!

Mathematics in life.
In fact, there is mathematics everywhere in our lives, such as wonderful circles.
Circles are the most common graphics in life, and people apply them almost everywhere. In the car, on the road, at home, and even in the air, you can always see the trail of the circle.
One of the great benefits of circles is that they have no edges and corners. Why can a car make a car run fast without a bump in the person sitting in it? It's because the wheels of the car are round.
When you're bowling, why is the bowling ball a sphere instead of a cube or cuboid? It is because the friction between the sphere and the ground is the smallest, the speed slows down for the longest time, and the speed is not easy to change. It is precisely because of the absence of edges and corners that people call circles and spheres the most beautiful plane shapes and the most beautiful three-dimensional shapes.
The circle is recognized as the most economical figure. Everyone knows that when the circumference is the same, the area of a circle is larger than any other shape. According to this reason, people designed a round manhole cover, because when the round manhole cover is placed perpendicular to the ground, it will not fall into the manhole like a square or rectangular manhole cover, but will be firmly stuck on it.
How can such a cute graphic not be favored by people?
In addition to circles, there are also some three-dimensional shapes related to circles, such as cylinders and spheres, which also play a pivotal role! With the same area of material, the volume of the cylinder is the largest, and likewise, its supporting force is also the largest. Tree trunks, bamboo, buckets, etc., all have cylinders applied.
There is also the decimal point, mathematics, which is everywhere in our lives. Gaussian quadrature and tree planting problems ......We are amazed by these wonderful laws of mathematics. Let's go on a journey to find the amazing digital!
The decimal point is everywhere in weight, **. Everywhere it shifts to the right to represent expansion and left to represent shrinking, and this magical decimal point unveils our digital journey today.
We sometimes don't get whole numbers in our measurements and calculations, and this is where the decimal point comes in. The decimal point has a huge "right" to its right, with the decimal part to its right and the integer part to its left. It has a lot of prestige in the digital world because:
Its movement changes the size of the number. It has two ways to change the size of the numbers: 1) the numbers are reversed, and 2) the decimal points are moved.
In life, the decimal point changes a lot of ends when it turns into a singular number, and a turn into a complex number, the decimal point not only moves the decimal point to change the size of the number, but also uses multiplication and division to change the size of the number, multiplication means to move to the right, move one place and expand by 10 times; In addition to indicating a move to the left, move one bit to shrink by a factor of 10.
The decimal point is magical, and there are many magical laws in life, let's explore them together!
