Dad has the habit of smoking. I often tell him to give up smoking, but he doesn't listen. Today, I made an account with my father: he smoked a box of "Double Happiness" and a box of 10 yuan cigarettes every day, and spent 3650 yuan every day for 365 days. Smoking also affects your health. It costs more than 300 yuan to buy medicine. In this way, dad spent more than 4,000 yuan a year on smoking and medicine. Dad said, "I'm going to quit smoking soon!" " "

This is an article "math diary" written by students of Jianghua Primary School in Pengjiang District. Recently, the reporter interviewed the teachers and students of Jianghua Primary School with great interest.

Many students are writing "math diary"

"math diary" is to write mathematical problems found in life into a diary. So, how did the "math diary" of Jianghua Primary School come into being? It is understood that once, when a math teacher at school was reading a magazine, it suddenly occurred to him: if I can write a diary about the process of learning math, can I contribute? Soon, she started to make the class try to write "math diary". Later, she extended her experience to other classes in the school. Now many classes in Jianghua Primary School are writing "math diary".

Teacher Li of Class Two (2) said that math diary was welcomed by the students. "math diary" is different from the usual diary. Students only need to express their problems clearly in the simplest language, so second-year students can also write their own "math diary". According to Teacher Li, math problems can be seen everywhere in life. Writing "math diary" can help students find vivid examples in life according to what they have learned in class, find problems, analyze problems and solve them at any time, improve their self-study ability and logical thinking ability, cultivate their sensitivity to mathematics, and stimulate their interest and enthusiasm in learning mathematics. Students keeping diaries can also exercise their writing ability and make Chinese and mathematics complement each other. The teacher will annotate every "math diary" written by the students. Miss Li said that reading "math diary" is like communicating with her classmates, and she can understand what they think and learn, so she likes reading her classmates' "math diary" very much.
