1, teaching content:

"How many days are there in a week" is the content of "multiplication formula (2)" in the second lesson of Unit 7 in the first volume of Grade 2 of Beijing Normal University Edition.

2. The position, emphasis and difficulty of teaching materials:

The multiplication formula is the beginning for students to learn multiplication, and it is the basis for students to learn division in tables and multiplication and division of multiple digits in the future. The content of the textbook is presented after students learn the multiplication formula of 2-6. Because they already have the foundation to learn the multiplication formula of 2-6, the presentation form of the textbook does not give a complete multiplication formula and a complete formula, which is intended to let students actively explore and summarize the multiplication formula of 7 and improve their autonomous learning ability. By learning the multiplication formula of 7, it lays a good foundation for learning the multiplication formula of 8 and 9 and calculating the multiplication and division method of 7, which provides a powerful help for improving students' computing ability.

Proficient in multiplication of oral tables is the most basic computing ability that every student should have. Therefore, the focus of this lesson should be to let students understand the formation process of the multiplication formula of 7; The difficulty is how to remember and use multiplication formula to solve practical problems in life.

3. Teaching objectives:

① Through observation and exploration, let students know the formation process of the multiplication formula of 7.

② Cultivate students' abilities of observation, judgment, cooperation and communication and language expression through teaching activities.

(3) Let students experience that there is mathematics everywhere in life, and they will use mathematical knowledge to solve problems in life.

Second, pay attention to innovation and choose teaching methods.

According to the teaching requirements, combined with the characteristics of teaching materials, in order to better highlight key points, break through difficulties and complete teaching tasks. I adopted:

1. The curriculum standard of situational teaching method points out that mathematics teaching activities must be based on students' cognitive development level and existing knowledge and experience. Therefore, the creation of scenes should be based on students' life experience and knowledge background. At the beginning of the new lesson, show the dialogue between naughty children, smiling children and jingling children by observing the situation map. Naughty children say "the sports meeting will be held in two weeks" and smiling children say "my birthday will be in three weeks", which leads to today's topic "How many days are there in a week", and the exploration of new classes begins under this circumstance.

2. Game teaching method. Game activities are deeply loved by junior students and can fully mobilize their enthusiasm. The teaching concept of the new curriculum reform has repeatedly put forward that students should "learn by doing and play with it". In my class, I designed games such as "Answer first", "Driving a train", "Happy Wheel", "Going home by formula" and "Dictation". Consolidate old knowledge and apply new knowledge in the game.

3. Group cooperation teaching method. It embodies the mathematics learning mode of "independent exploration, cooperative communication and practical innovation", completes the learning task in discussing "multiplication formula of 7" and "how to remember formulas", and cultivates students' awareness of mutual cooperation and communication. This kind of teaching can better reflect the function of "students are the masters of mathematics learning and teachers are the organizers, guides and collaborators of mathematics learning".

In addition, music is a panacea for cultivating people's minds and an effective tool for regulating emotions. Also in order to increase students' interest in learning, let students operate in relaxed and happy music. And encourage students to think more and express their views in the form of "applause and praise".

Third, cultivate ability and guide learning methods.

Curriculum standards point out that effective mathematics learning activities can not only rely on imitation and memory, but also practical, independent exploration and cooperative communication are important ways for students to learn mathematics. At the same time, pay attention to the guidance of learning methods. In the teaching of this lesson, students mainly use the following learning methods:

1. In the teaching of independent inquiry method, students' dominant position and participation in the process of knowledge formation are emphasized, so that students can explore independently and cultivate their ability to explore actively. Because teaching activities are no longer teachers' "preaching", more time should be spent in the process of students' independent exploration. Therefore, the whole class did not come up with a complete formula and formula, but let the students carefully observe, compare and analyze the multiplication formula and formula law of 7 in activities such as watching, filling, thinking and doing.

2. Game learning method

. Apply learning results in games and apply mathematics knowledge in real life. In class, I designed games such as "Answer first", "Driving a train", "Happy Roulette", "Going home by formula" and "Reciprocating formula" to let students learn boring formula knowledge in happy games. It fully mobilized students' enthusiasm for learning, enlivened the classroom atmosphere, and made the whole classroom alternate with static and clear in depth.

3. Observe and discuss. Students observe the pictures, discuss "how to write the multiplication formula of 7", observe and discuss the formula rules in the new formula, so as to memorize them and let students upgrade their perceptual knowledge to rational knowledge in their independent exploration.

Fourth, innovate thinking and optimize procedures.

According to the content of the textbook and students' cognitive level, I designed the following teaching process:

(1) Review old knowledge.

① Review 2-6 formulas.

2 formula solitaire.

(3) Formula answer.

Let the class recall "2-6 multiplication formula". This is not only to test whether they master and remember, but also to pave the way for the teaching of this course.

(2) Set the situation and explore new knowledge.

In this link, I designed four teaching activities:

1, write a formula.

This is the focus of this lesson, mainly through students' independent observation of pictures, exploring and summarizing the formation process of the multiplication formula of 7, and memorizing it.
