1, date and subject. Write the date at the beginning of the diary and indicate that the diary is about mathematics. For example: September 4, 2023, math diary.

2. What did you learn today? Briefly describe what knowledge points or concepts you learned in today's math class. For example, today we learned the division operation and the calculation method of rectangular area.

3. Knowledge points mastered. List the knowledge you have mastered, or describe your understanding of what you have learned today. For example, I have mastered the basic principle of division and can use division to solve practical problems. I also learned how to calculate the area of a rectangle by multiplying its length and width.

4. Solutions to problems. Describe your methods or strategies to solve math problems in class. For example, after doing a lot of exercises, I found that backward deduction can help me solve the division problem. When calculating the rectangular area, I used the method of memorizing the formula. I calculated the length and width first, and then multiplied them.

5. Self-evaluation and feelings. Evaluate yourself according to your performance and academic achievements in class and write down some of your feelings or experiences. For example, I did well in today's math class and was able to solve most problems independently. Through this lesson, I deeply understand the division and the calculation method of rectangular area, and feel that mathematics has become more interesting.

6. summary. Summarize the gains and importance of today's math class in one or two sentences. For example, today's math class let me better master the division and the calculation method of rectangular area, which is very helpful to solve practical problems in daily life.

The significance of writing about math diary

1, deepen understanding: By writing math diary, we can understand and digest the mathematics knowledge learned in class more deeply. Writing down our understanding of mathematical concepts, formulas and problem-solving methods can help us deepen our grasp of these knowledge.

2. Thinking and Analysis: Writing about math diary can make us think and analyze mathematical problems. While recording the problem-solving process and thinking route, it is necessary to sort out ideas, analyze the key points and difficulties of the problem, and improve the problem-solving ability.

3. Sorting out mistakes and weaknesses: In math diary, we can record mistakes and mistakes, and reflect and summarize these problems. By sorting out our mistakes and weaknesses, we can help us find and make up for the shortcomings in mathematics learning.

4. Establish mathematical thinking habits: Writing about math diary is a way to cultivate good mathematical thinking habits. By recording the mathematical thinking process and problem-solving experience every day or regularly, we can gradually develop the habit of thinking actively, analyzing problems and finding solutions.
