Interview and lecture notes on primary school mathematics teaching resources

Interview and lecture notes on primary school mathematics teaching resources

As a teaching worker, it is inevitable to prepare a lecture, which can better organize teaching activities. So how should I write a speech? The following is an interview presentation of primary school mathematics teaching resources collected by me, hoping to help everyone.

First of all, talk about textbooks.

1. Teaching content: Unit 3, Section 3, Book 12, Elementary School Mathematics, People's Education Edition (textbook 35 pages, Example 2, Example 3, problem solving. )

2. teaching material analysis

The teaching design of "solution ratio" firmly grasps the "basic nature of proportion" and plays a bridge role between proportion and simple equation, which better embodies the leading role of teachers and the main role of students. At the same time, it provides many opportunities for students to participate in the teaching process and show their talents, and has achieved good teaching results.

3. Teaching objectives:

According to the requirements of the syllabus and the characteristics of teaching materials, combined with the actual level of sixth-grade students, the following teaching objectives are determined: the teaching objectives are divided into three dimensions:

(1), cognition: Make students know the meaning of solution ratio and learn to apply the basic properties of solution ratio.

(2) Ability: enable students to further consolidate the significance of ratio and proportion and further understand the basic nature of proportion.

(3) Emotion: cultivate students' good study habits.

4. Teaching emphases and difficulties: According to the arrangement characteristics of teaching materials and the teaching content of this lesson, the following teaching emphases and difficulties are determined: 1, to understand the significance of the solution.

5, said the teaching method:

According to the content and arrangement characteristics of the teaching materials in this section, in order to better highlight the key points and break through the difficulties, according to the students' cognitive rules, and following the guiding ideology of teacher-oriented, students-oriented and training-oriented, students are mainly allowed to master knowledge in the learning process of "calculation-observation, comparison-generalization-application".

6. Talking about learning situations and learning methods: Students learn to solve the ratio after learning the basic properties of ratio, ratio and proportion, and already know the internal and external terms of proportion. In order to better reflect that students are the masters of learning, students mainly adopt the methods of practice, explanation and self-study counseling.

Second, the program design

Classroom teaching is an important way for students to acquire mathematical knowledge and develop their abilities. Based on this, I designed the following teaching design.

(A) the introduction of new courses

Teacher: Do you want to travel? I want to go to Beijing World Park with my teacher now, ok? Show the relevant pictures in the courseware, so that students can know the pictures and carry out appropriate education. This design is mainly to attract students' attention to this class. )

Review and introduce the new pyramid map made according to 1: 25. The model height is 5.86m, and the actual height is146.5m..

(1) Students, please write a ratio with these four numbers.

(2) The students have written out the proportion. Who will say what proportion is? (praising students)

(3) What is the basic nature of proportion? (Student Qi said)

2. According to the basic properties of proportion, rewrite the above proportion into equal product formula. (blackboard writing)

Teach new courses

1, example 2.

(1), Question: What is the difference between this example and the review question just now? Can we use the basic properties of proportion to find the unknown x? Think for yourself first, then write. )

(2) Students report the solution process.

(3) Revealing Example 2 is an unknown item in the proportion. (blackboard writing: finding the unknown term in the proportion) As can be seen from Example 2, according to the basic properties of the proportion, if any three terms in the proportion are known, another unknown term in this proportion can be found. This unknown term of finding proportion is called solution ratio. (blackboard writing topic)

Students, will you apply the basic nature of proportion to the solution? (yes)

Show Exercise 812 = x 45.

Students finish independently and revise collectively.

2. Teaching example 3.

Example 3: (omitted)

Please use the basic properties of proportion to solve this proportion, find out the unknown term X, and think for yourself first to see if there is any way. Try to do it again. Name one person who is performing on the blackboard, and the rest of the students are performing in the exercise books. Ask students to talk about their ideas, what is the basis of the first step, and explain the writing format of solution ratio to students.

Then the teacher pointed out that the solution ratio is generally to write the formula of equal product according to the basic properties of proportion, and then solve the unknown X.

3. Show exercises (omitted)

Students finish independently and revise collectively.

4. Summarize the method. Question: according to the basic nature of proportion, how to treat the solution ratio?

Exercise requirements: students complete independently, name the blackboard, and correct collectively.

Course summary:

What did you learn in this class? How do you apply the basic nature of proportion to solve proportion?

Say blackboard writing design:

According to the learning characteristics of students, it is easier to master the knowledge learned in this lesson. I designed the following blackboard writing. (omitted)
