20 14 Design of Mathematics Lecture in Anhui Teachers' Recruitment Primary School: Volume Calculation of Cuboid and Cube

First of all, talk about textbooks.

(A) Teaching content

People's Education Press Nine-year Compulsory Education Six-year Primary School Mathematics Volume 10 Unit 2 Section 3 Volume Calculation of Cuboid and Cube.

(B) teaching material analysis and target setting

Cuboid and cube are the most basic three-dimensional figures. It is a leap for students to learn three-dimensional graphics on the basis of knowing some plane graphics. This unit basically understands the characteristics and properties of cuboids and cubes, learns the calculation of surface area, and grasps the concept and common units of volume. In this lesson, we will learn the volume calculation of cuboids and cubes, know the source of the volume formula, and master the meaning and usage of the formula. Volume calculation of cuboids and cubes is the basis of continuing to learn geometry knowledge in the future. According to the analysis of the structure and content of the above textbooks, and taking into account the psychological characteristics of students' existing cognitive structure, I have formulated the following teaching objectives:

① Knowledge objective: To enable students to master the formulas for calculating the volume of cuboids and cubes and learn to calculate the volume of cuboids and cubes.

② Ability goal: to cultivate students' practical operation ability, reasoning ability and ability to solve practical problems with knowledge.

③ Emotional goal: guide students to experiment and deduce the volume calculation formulas of cuboids and cubes. Let students experience the process of exploring knowledge, stimulate students' enthusiasm for exploration, and cultivate students' exploration and challenge. At the same time, the infiltration theory comes from the concept of practice.

(3) Teaching emphases and difficulties.

According to the relationship between cuboid and cube, the key and difficult points should be located in the following aspects:

(1) teaching emphasis: guide students to explore the formation process of cuboids and cubes.

(2) Teaching difficulty: understanding the meaning of the formula.

Second, talk about learning.

Volume is a new concept for students. Before class, students have a preliminary understanding of volume and its units, and have a vague understanding of the volume of objects. In teaching, teachers should pay attention to the cultivation of students' spatial concept, proceed from students' reality, make full use of and create conditions to make students study in a relaxed and happy atmosphere; The interactive multimedia course is used to guide students to enrich their perception of the body by observing, measuring, combining, drawing and making objects and models, so as to cultivate their preliminary spatial concept and abstract generalization ability.

Third, oral teaching methods

Dostoevsky said: A bad teacher gives up the truth, while a good teacher teaches people to discover the truth. According to the requirements of the new curriculum standard, I think I will change my mind, not just impart knowledge, but become a guide, supporter and collaborator of children's life, and strive to create suitable activity environment and learning conditions for them, so that they can actively explore, find problems and sum up the rules themselves. Based on children's cognitive characteristics, the teaching of this course emphasizes entertaining and intuitive images, and adopts heuristic and inquiry teaching methods to let students participate in it and draw their own conclusions.

Fourth, the methods of speaking and learning
