Students have learned addition and subtraction, and this section is the beginning for students to learn multiplication. Because students don't have the concept of multiplication, and it is difficult to establish this concept, in this case, the textbook has a special "Preliminary Understanding of Multiplication" section at the beginning to let students know the meaning of multiplication and lay a very important foundation for learning other knowledge of multiplication in the future.

The textbook attaches great importance to students' practical operation. First, it is suggested that students make a pendulum and calculate it, and compare it with the multiplication formula through physical diagram, addition formula and multiplication formula. The reading and meaning of multiplication formula are in contrast with multiplication formula, so that students can be familiar with multiplication initially and learn to read and write multiplication formula in the process of being familiar with multiplication.

From this, we can clearly draw two knowledge points: one is to be familiar with the same addend and the number of the same addend, so as to introduce multiplication, which is a main line of this teaching; Second, the writing and reading of multiplication formula is the basis for understanding the meaning of multiplication and actual calculation. Through the above understanding and analysis of the teaching materials, we can determine the following teaching objectives, teaching priorities, difficulties and priorities.

Teaching objectives:

1, make students familiar with the meaning of multiplication and master the reading and writing methods of multiplication formula.

2. Cultivate students' initial logical thinking ability of analysis, comparison, synthesis and abstract generalization.

3. Infiltrate mathematics knowledge from practice and cultivate students' enthusiasm for learning mathematics. Teaching emphasis: be familiar with the meaning of multiplication, and be able to add the same addend and change it into multiplication formula.

Teaching focus:

Identify the same addend

Teaching difficulties:

Understand the different meanings of two numbers before and after multiplication

Teaching methods and learning methods

1。 Correctly apply the law of knowledge transfer, pay attention to innovation, grasp the connection point between old and new knowledge, and reflect the teaching thought of reviewing the past and learning the new.

Using intuitive teaching methods, let students operate in time, pay attention to arouse students' learning enthusiasm, and make students cooperate with each other in various sensory activities, so as to think in observation and operate in thinking. On the basis of demonstration and drawing, teachers abstract methods in time, and then compare and contrast them to further strengthen the new knowledge they have learned.
