1. Life shows laziness in mathematics.
That is to bring students into society and nature, choose a typical mathematical scene from life as the object of students' observation, and show it clearly in front of students with the teacher's language description.
2. Demonstrate the mathematical situation in kind
That is, taking the object as the center and setting the necessary background slightly to form a whole to demonstrate a specific mathematical situation.
3. The picture reproduces the mathematical situation.
Pictures are the main means to display images. Reproducing mathematical situations with pictures is actually visualizing mathematical content. Mathematical illustrations, specially drawn wall charts, clip art and stick figures can all be used to reproduce mathematical situations.
Mathematics activities refer to all kinds of activities related to mathematics learning that students participate in in classroom teaching. Correctly organizing and attracting students to participate in this activity can expand students' knowledge, cultivate their interest in learning mathematics and develop their mathematical talents.
The activities include: lectures on popularizing mathematics, commemorating mathematicians, mathematical fairs, mathematical garden publications, mathematical competitions, mathematical groups, and students' extracurricular reading, translation and writing mathematical papers.
Schools and teachers should pay attention to selecting and organizing activities that are educational, suitable for students' age characteristics, rich in content and diverse in forms, attracting more students to participate voluntarily, organizing, purposefully and effectively, and giving full play to students' independence and creativity.
It is a necessary supplement to classroom teaching and can reflect the principle of teaching students in accordance with their aptitude. It is called "the second classroom". Correctly organizing and attracting students to participate in mathematics extracurricular activities can expand students' knowledge. Cultivate and develop students' interests, talents and specialties, and create favorable conditions for further study of mathematics and career choice.
Activities can be carried out by making teaching AIDS, guiding reading mathematics books and periodicals, running mathematics wall newspapers, compiling mathematics essays, and making special reports (such as Chinese and foreign mathematics history, stories of famous mathematicians, popular introduction of some modern mathematics theories, etc.). ), hold a math story, hold a math contest, hold a math game, and measure on the spot.
