Goals in the field of mathematics: 1. Understand the decomposition and composition of numbers, and know that a number can be divided into two parts, and these two parts together are still the original number. 2. Know all the components of each number from 2 to 10. 3. Understand the interchangeability and complementarity contained in the composition of numbers, and use them to deduce the composition of new numbers. 4. Take measures: In the teaching activities of science and mathematics, I will use teaching materials and teaching AIDS suitable for children's age characteristics to better convey the knowledge in the field of science and mathematics to every child and strive to achieve the above goals. 5. Use teaching AIDS in teaching activities: digital cards, building blocks, slides, wall charts, teaching pictures, teaching CDs and other teaching AIDS to make each lesson more effective.

The determination of teaching objectives is the basis for the smooth development of practical comprehensive application courses, and it is also the starting point and destination of the whole teaching activities. Undoubtedly, the understanding of practice and comprehensive application process is the basis and necessary prerequisite for the orientation of oral labeling teaching.

Practice and comprehensive application, as a field, place great emphasis on connection and synthesis, but when it comes to a class or a special topic, in what scope should it be "connected" and to what extent should it be "integrated"? There's plenty of room here. However, no matter what field, subject and method the activity involves, the teaching objectives should be specific and clear in order to make the activity effective. In addition to giving students a good emotional experience and feeling the role of mathematics in daily life, they should also find a foothold in their activities and consider what kind of mathematics knowledge to rely on to maintain their proper "mathematics taste".
