The basic idea of the new primary school mathematics curriculum is 1. The life-oriented mathematics teaching of mathematics curriculum should start from students' life experience and existing knowledge, take the practical problems that students have experienced and are easy to understand as materials, and pay attention to the connection with the teaching knowledge that students have already known and experienced, so that students can understand the teaching knowledge and construct the mathematical knowledge structure through independent activities in familiar things and specific situations. 2. Let students witness the formation of mathematical knowledge. The only correct way to learn mathematics is to implement "re-creation". Inquiry learning emphasizes that students gain personal experience by participating in learning activities similar to scientific research, which is "re-creation". Students must be allowed to see the formation and development of mathematical knowledge and experience how to "do mathematics" by themselves. 3. Changing students' learning style "Curriculum Standards" points out: "Students' mathematics learning and activities should be a vivid, active and personalized process." Hands-on practice, independent exploration and cooperative communication are important ways for students to learn mathematics. " This is the core idea of this curriculum reform. 4. Teachers should change their teaching methods. Curriculum standards point out that "teachers are organizers, guides and collaborators of mathematics learning". In teaching, teachers should carefully organize classroom teaching, effectively guide students to participate in mathematics activities, and sincerely cooperate with students to create a new classroom culture. 5. The essence of evaluation is to promote the development of students. New curriculum evaluation pays attention to students' all-round development. The main purpose of evaluation is to fully understand students' mathematics learning process, inspire students' teaching and improve teachers' teaching. An evaluation system with diversified evaluation objectives and methods should be established. Evaluation should pay attention to students' learning achievements, but also pay attention to students' emotions and attitudes in teaching activities, so as to help students know themselves and build up confidence. 6. Pay attention to the application of modern information technology.
