The teaching objectives, teaching emphases, difficulties and teaching process of the first class of mathematics in the first grade of primary school can be arranged as follows:

1, teaching objectives. First of all, let students know that they are first-grade students in primary school, strengthen the education of learning routines, observe classroom routines, and cultivate students' good study habits. Secondly, through telling stories, let students know that there is mathematics everywhere in life, stimulate students' interest in learning mathematics and enhance their self-confidence in learning mathematics well.

2. Teaching focus. The teaching focus of this class is to cultivate students' habit of listening carefully and raising their hands before speaking.

3. Teaching difficulties. Stimulate students' interest in learning mathematics and establish self-confidence in learning mathematics well.

4. Teaching process. First of all, teachers can introduce themselves and have basic interaction with students, so that students can feel the care of teachers and the warmth of the classroom. Secondly, let students know the close relationship between mathematics and life through some simple math games or stories, such as the application of simple addition, subtraction, multiplication and division in daily activities such as shopping and candy distribution. This can make students understand that mathematics is not out of reach, but closely related to life.

Then some basic arithmetic teaching can be carried out, such as horizontal and vertical comparative observation, formula analysis, teaching students how to calculate addition and subtraction, and problems that should be paid attention to in calculation. When students encounter difficulties in summing up, teachers can use examples in blackboard writing as a starting point to guide students to sort out their knowledge.

Finally, consolidate the practice and expand the innovative part. Teachers can use counters and other teaching AIDS to assist teaching and complete exercises on related topics, so that students can learn while operating and deepen their memory. At the same time, we can also set some open questions to let students play innovative thinking in solving problems and improve their mathematical ability.
