1. Teaching content: The textbook * * * includes seven units: multiplication, symmetry, translation and rotation of decimal, elementary school division, simple equation, polygon area, factor and multiple, statistics and total review.

Second, the analysis of academic situation: there are 28 students in the class. Most students' observation, memory and thinking ability are in line with the characteristics of age and grade, and they have certain study habits, good learning attitude and strong confidence in learning mathematics. The analysis ability of students' information window has been improved to some extent.

Third, teaching objectives: students master the calculation method of decimal multiplication and division, and can skillfully perform written calculation and simple oral calculation of decimal multiplication and division; Will use the "rounding method" to get the approximate value that the product sum quotient is a decimal; Know cyclic decimals.

4. Teaching emphasis: Students systematically combed the knowledge in the fields of number and algebra, space and graphics, statistics and possibility, comprehensive application, etc., further improved their math skills, strengthened their awareness of solving problems, developed their abilities, and laid a good foundation for further study.

Fifth, teaching measures: the design of exercise questions, strive to be close to students' real life and ideological education factors, combined with the content of teaching materials, timely and moderately carry out ideological education for students. Through the calculation and solution of application questions, students' good learning attitude and good habit of checking after the questions are cultivated.
