First-grade pupils think better in images, but worse in abstractions. According to the characteristics of this age, they are easy to remember vivid, vivid and concrete things, but have no interest in boring, single, boring and abstract mathematics knowledge. Therefore, I attach great importance to intuitive teaching in mathematics teaching. Through various sensory activities such as listening, doing, speaking and thinking, students gradually accumulate rich perceptual knowledge and gradually become interested in new things, which is the main means for students to learn new knowledge and promote the development of thinking.

For example, when I teach the understanding of numbers within 10, students can form a correct concept of numbers by putting sticks and drawing pictures. When teaching the decomposition of 5, I vividly drew it as a hand, and asked the students to take out five sticks, first two in the left hand and three in the right hand, which became ***5, and asked the students to look at their hands and say, "5 can be divided into 2 and 3." Then let the students take 3 in their left hand and 2 in their right hand. Ask the students to look at their hands and say, "5 can be divided into 3 and 2." Use five sticks and let the students speak with sticks. Students quickly master the composition decomposition of 5 and the addition and subtraction of 5. As shown in the figure below:

Care and help them, be persuasive, and make them love learning.

The biggest obstacle to students' progress is their lack of confidence in learning and dislike of learning. If you don't understand in class, you can't do your homework, you always fail in exams, and you can't see the "way out", so you gradually lack confidence in learning well. Imagine, if a student has no confidence in learning, how can he have the motivation to learn? The primary problem of improving poor students' academic performance is to establish learning confidence. As the saying goes, "self-confidence is the first secret of success", which makes them love learning. ① According to the view that poor students are born stupid, we should use specific reasoning methods to get rid of the superstition of "born stupid", emancipate our minds and establish confidence in progress. It is not easy for poor students to make greater progress. Teachers should pay attention to their progress, find their slight progress, affirm it in time, and improve their learning confidence. (3) create conditions for them to experience the happiness of learning and progress. When he makes progress, he should be praised in time, so that all the students in the class can warmly welcome him and create a harmonious atmosphere of progress. Parents should also praise him in time, and let him experience the progress in his study as the most enjoyable thing. If he is interested, he will gradually be full of sense of accomplishment.
