The second volume of fourth grade mathematics 1 work plan 1. Analysis of students' current situation;
There are 4 1 students in Class One, Grade Four. Students are interested in mathematics, have strong acceptance and correct learning attitude. From the perspective of students' knowledge, most students have a good grasp of what they have learned and can apply what they have learned to practice. Most students have a good command of oral calculation, calculation and application problems, while a few students (Zhao, Fang Bo) can't use them, but the whole class has a strong learning atmosphere.
Judging from students' study habits, some students (Hu Zhengyi, Pei, Jiang Zhilong) have poor study habits, such as writing slowly, copying wrong numbers, counting irregularly, and not being able to do problems with a ruler. For these reasons, the result is not ideal.
In terms of class routine, you can listen attentively and answer questions completely in class. However, some students (Zhao, Jiang Zhilong, Hu Zhengyi, Pei) are playing in class. When discussing problems in groups, some students are lazy and have poor teamwork ability.
In view of the above problems, this semester, while correcting students' learning attitude, we should set practical goals for all, fully mobilize students' learning enthusiasm and initiative, strengthen discipline education and routine training, strengthen the cultivation of their various abilities to learn mathematics, cultivate their good study habits, improve their ability to solve problems, and help every child learn valuable mathematics.
