The new curriculum standard points out that it is necessary to change the teaching design that pays too much attention to class hours and promote the teaching design to reflect the content of mathematical knowledge. The new curriculum standard points out that it is necessary to change the teaching design that pays too much attention to class hours and promote the teaching design to reflect mathematics as follows:

The new curriculum standard points out that it is necessary to change the teaching design that pays too much attention to class hours as a unit, promote the overall teaching design of the unit, and reflect the integrity and systematicness of mathematical knowledge. This is helpful to change the disadvantage that traditional teaching pays too much attention to knowledge points and skills and ignores the connection and integrity of mathematical knowledge.

The whole teaching design of units refers to the division of mathematics courses into units according to the knowledge system from the overall point of view, and the systematic teaching design and arrangement are carried out in combination with the actual situation of students and the characteristics of disciplines. This teaching design can help students better understand the relationship and structure between mathematical knowledge and form a complete mathematical knowledge system.

In the teaching design of the whole unit, we should pay attention to the following points:

Overall planning: the overall planning and design of the whole period or grade of mathematics knowledge, clear the teaching objectives and contents of each unit, and ensure the coherence and integrity of teaching.

Highlight the key points: We should highlight the key points and difficulties of each unit and make targeted teaching design and arrangement according to the actual situation of students.

Pay attention to connection: pay attention to the connection and integration between mathematical knowledge, organically combine knowledge points and skill points to form a complete knowledge system.

Diversified evaluation: we should adopt diversified evaluation methods to evaluate students' learning comprehensively, objectively and scientifically, so as to better guide students' learning and teachers' teaching.

In a word, promoting the whole teaching design of the unit is one of the important requirements put forward by the new curriculum standard, which is helpful to improve the quality and effect of mathematics teaching and cultivate students' mathematical literacy and innovation ability.
