Psychological research shows that people's thinking level when they are depressed is only half of that when they are in high spirits. Therefore, in classroom teaching, teachers should try their best to create situations, adjust students' psychology to the best state, keep students in a good state of positive thinking, and thus activate innovative thinking.

Second, hands-on operation to promote the development of thinking

Hands-on operation is an important teaching activity to cultivate students' thinking and innovation ability, and it is also an important method for students to actively explore and acquire knowledge. Mathematics knowledge is abstract, boring and difficult to understand, which makes some students lack interest in mathematics. And hands-on operation is one of the effective ways to stimulate students' interest in mathematics learning. In teaching, using the active and curious psychology of primary school students, starting from the familiar life situations and interesting things, we can provide opportunities for observation and operation, which can give full play to students' conscious initiative in learning, let students turn abstract mathematical knowledge into vivid actions in interesting operations, and get a correct understanding from their feelings.

Third, the clever use of evaluation language to stimulate interest in learning

Language is the direct embodiment of teaching ideas and the most widely used and basic information carrier for teachers. Teachers' evaluative language in classroom teaching can stimulate students' interest in learning, mobilize students' positive thinking and cultivate good emotions. It is the fundamental task for teachers to improve the effectiveness of mathematics teaching by adopting various appropriate methods and means to turn abstraction into concrete and boring into interest.
