In order to effectively improve students' quality and implement the requirement of "students' all-round, sustained and harmonious development", in mathematics teaching, we should completely change our educational concept, not let students only solve mathematical problems, but more importantly, let students experience the role of mathematics and cultivate and improve their mathematical literacy.

For example, in the teaching of percentage application, the teaching design of this course is designed under the guidance of the new curriculum standard concept and according to the actual situation of the students in this class. In this lesson, "Please choose the percentage you are interested in and try to make up a percentage application problem". Students release the shackles of book application problems and teachers' thinking and boldly imagine and discuss.

From the actual effect, different students have different ways of thinking and solutions. Judging from the implementation, the whole class is in high spirits and full of interest.

Therefore, I think students should be given more trust in "letting go" and less guidance in "caring" in teaching, so that students can boldly fight freely in the wave of learning and find their own problem-solving strategies and learning methods. Only students with brains, personalities and abilities can emerge as the times require.
