Learning this rule is not only the theoretical basis of decimal multiplication and division, but also the software size of the mutual rewriting of composite numbers and decimals: unknown operating environment: Win9X/2000/XP/2003/ authorization mode: free version recommended level: 2008-07-2617:12: 59 "Generation and significance of decimals". Students can further understand the meaning and nature of decimals. The focus of this course is to make students clear about the generation and meaning of decimals, the relationship between decimals and fractions, and the counting units of decimals, so as to have a clearer understanding of the concept of decimals. The difficulty in teaching lies in the size of the software: unknown operating environment: Win9X/2000/XP/2003/ Authorization mode: free version Recommended level: 2008-07-26 1 7:10: 51Decimal Preliminary Understanding Lecture [Four-year Mathematics Lecture] Let's start with the textbook. Talk about the contents of the class: Nine-year compulsory education, Six-year primary school mathematics, Volume VII, P 1 7-18 cases,1and Example 2, and "Do a problem and practice Question 28 1-3". 2. The position and function of teaching content: The initial understanding of decimals is based on students' mastery of four operations within 100 million yuan and their initial understanding of fractions. This lesson includes understanding decimal numbers and their reading and writing. Knowing a decimal is the most basic knowledge in the initial understanding of decimal, and its learning not only helps students to accurately determine the size of software.

Second, the teaching goal enables students to further master the reading and writing rules of multi-digits. 1, so that students can further master the method of finding the divisor of a number greater than 100 million. 2. Let students understand the relationship between the parts in the four operations. Thirdly, the teaching emphasis can make students understand the relationship between the parts in the four operations. Fourth, the teaching difficulties use the relationship between the parts of the four operations to solve practical problems and improve the ability to solve problems. 5.

However, mathematics comes from life, and life cannot be separated from mathematical knowledge. Primary school mathematics itself involves some specific problems, which are inseparable from students' daily life. So how to integrate computer multimedia-assisted teaching with classroom teaching? Therefore, I think the effectiveness of the modernization of educational means lies in the size of the teacher's exploration class software: unknown operating environment: Win9X/2000/XP/2003/ authorization mode: free version Recommended level: 2008-07-1510: 37: 58 Fourth grade math activity class "Saving energy" [four years 2 Significance and function of the teaching material: This activity enables students to investigate the water and electricity consumption at home last month and exchange and compare in groups. * * * On the one hand, it can consolidate the previous decimal knowledge, on the other hand, it can let students gradually get in touch with social life and learn some common sense in real life.
