Mathematics textbooks for Grade One can stimulate students' interest in learning, so we should pay attention to guiding students to look directly at the views in the textbooks. For example, students can see who is more and who is less from the intuitive picture, but they should not only stay here, but also expand, for example, are there more boys or girls in the first group? Students will immediately count the number of boys and girls in the first group and make a correct judgment through comparative thinking.

2, contact with reality, hands-on operation

The first-year students are young and have limited thinking ability. When they are exposed to new knowledge, it won't have much effect if they rely on the teacher's endless explanation. They must arouse students' thinking interest, which requires practical operation. For example, when learning "left and right", students should know which side is left and which side is right, and guide the operation in time, so that students can do practical operations with books, pencil boxes and so on. Of course, teachers should carefully design operating passwords or procedures, and students will use their brains under the guidance of teachers and do what they think, thus promoting students' active thinking.

3, training language development thinking

First-year students are young, and it is also crucial to cultivate children's language expression ability. Whether students' thinking is reasonable must be expressed and tested by language, which requires students to be good at speaking their thoughts in an orderly way. Only in this way can it help to develop students' thinking. For example, students' thinking and language can be organically combined by posing, watching and talking, and comparing the size and length.

4. Expand training and draw inferences.

To train students' thinking ability, we should not only do some fixed questions, but also let students draw inferences from others and use them flexibly, which requires expanding training. For example, if you learn to write two addition formulas and two subtraction formulas with three numbers, you can train students to choose three numbers and write two addition formulas and two subtraction formulas. If the numbers given to students are 3, 6, 2, 5 and 8, students will choose: 3, 2 and 5 after thinking; 6、2、8; 3, 5, 8, no doubt, cultivate students' thinking ability.

The thinking training of the first-grade primary school students is very important, especially the mathematical thinking training, which is of great help to the students' future academic study. I hope these methods are helpful to everyone!
