Pupils are naive, lively and active, and like all new and interesting things. Primary school mathematics teachers pay attention to creating effective teaching situations in teaching, which is not only conducive to the cultivation of students' mathematical thinking, but also can make students have a stronger interest in mathematics learning. Specifically, in specific teaching activities, teachers can create teaching situations that meet the learning needs of primary school students through detailed analysis of teaching content and students' learning ability. For example, there are knowledge points of geometric figures in the textbook of the first grade of primary school. Teachers can try to change the boring teaching mode of simple explanation, and build the geometry with students with cardboard, glue and safety scissors prepared before class. In the process of building, the characteristics of edges, corners and surfaces of geometric figures mentioned in the textbook are interspersed, so that students can have a deeper impression on what they have learned in practice. Primary school math teachers can also encourage students to give full play to their thoughts and construct any geometric figure they imagine with cardboard in their hands, so that students' learning is not limited to math textbooks and students' innovative thinking ability is cultivated. Furthermore, the creation of teaching situation must be combined with students' hobbies, understanding ability and learning level. Primary school math teachers should communicate with other teachers and students before teaching and collect relevant information, so that situational teaching can get twice the result with half the effort.

Second, contact life and stimulate interest.

Mathematics comes from life and is finally applied to life. Life-oriented teaching is an effective way to cultivate students' mathematical thinking ability, which is more conducive to improving students' ability to use mathematical knowledge in life. For example, when teaching grams, kilograms and other measurement units, teachers can let the whole class weigh themselves first, and write down their own weights in kilograms, and arrange for students to go home and ask their parents how many kilograms they weigh, so that students can have a preliminary impression of what they have learned.
