Lecture notes on two-digit addition and subtraction application problems
Lecture content: addition and corresponding subtraction of first-grade textbooks
First, the position, function and significance of teaching content.
? Application of two-digit addition and subtraction? Teaching is carried out on the basis that students have learned dozens of numbers of addition and corresponding subtraction, which is the last stage of two-digit addition and corresponding subtraction, so it plays an important role in addition and subtraction within 100, which is one of the most basic knowledge for primary school students to learn mathematics and one of the basic skills that students must practice well. It is of great significance to lay a good foundation for students to further study mathematics.
Second, the teaching objectives and requirements
1, so that students can further master the calculation method of adding and subtracting two digits.
2. Cultivate students' ability to examine questions and solve practical problems.
3. Cultivate students to develop serious and careful good habits.
Teaching emphasis and difficulty: ask questions by looking at pictures.
Third, the choice of teaching methods and learning methods.
Teaching method: Creating situational method. In order to make students skillfully abdicate and subtract respectively, (1), first let students judge and correct after counting the numbers in the train, then, (2) explain the calculation process after the vertical calculation is completed, and (3) check at the same table to help correct. The thinking characteristic of first-year students is figurative thinking, and at the same time, the form of intuitive action thinking must be retained. Starting from students' favorite skipping activities, increase students' activities and hands-on activities, and guide students to move their eyes, talk and think, and learn with multiple senses.
Learning method: group cooperation and communication. According to the characteristics of teaching materials and students, we choose teaching methods such as self-study observation and group cooperation and communication. At the same time, in terms of learning methods, we choose the method of guiding students to read mathematics textbooks and perceive information, and organize discussions and exchanges for students to learn. In the preparation of learning tools and teaching AIDS, there should be small blackboards, cards and so on.
Fourth, teaching program design.
First, check the preview.
1, drive the train and do oral calculations.
2. Vertical calculation
7 1-28= 62-37= 9 1-82= 46+24=
Show me the calculation process on the stage.
What should I do if I use an upright type? Let students think independently.
What should I do if the number of 1-8 is not enough?
Important: When subtracting the tenth digit, don't forget to subtract the backward 1 first.
Ask students to talk about the calculation process when communicating.
3. Group discussion: Can you talk about what should be paid attention to in pen subtraction?
"In this way, through the combination of counting cards, formulas and answers to questions, students can sort out the relationship between old and new knowledge, infiltrate the active learning consciousness of progressive learning and constantly discovering problems, and prepare the necessary conditions for highlighting the teaching focus of this course, solving difficulties and smoothly implementing positive transfer.
Second, the introduction of passion.
Every morning, students like skipping rope. Now let's watch Obana Xiaogang's skipping competition.
Third, autonomous learning.
Look at the form and ask questions.
Xiao Gang of Kobanawa is having a rope skipping competition.
The first time and the second time.
Xiaohua 38 Xia 37 Xia
Xiaogang 44 down 39 down.
Let the students feel what the picture information says. Know what? This can arouse the enthusiasm of every student and encourage poor students. Teachers should let students choose a set of numbers, combine what students say, and use horizontal and vertical information to inspire and guide students.
(3) Organize discussion: What do you think? Talk about the process of thinking. Students have different ways of thinking, so guide them to talk about their own problems? what do you think? Encouraging students to think in many directions not only strengthens the teaching focus, but also fully mobilizes students' learning enthusiasm.
Fourth, organize the display of returns.
Ask questions:
(1), Xiaohua's second jump is less than Xiaogang's first jump, right?
(2) How many times did Xiaohua jump twice?
(3) How many times did Xiaohua jump less than Xiaogang for the first time?
(4) How many times did Xiao Gang jump for the second time?
Column comparison calculation
Verb (abbreviation of verb) expands new knowledge.
What other questions will you ask?
Teachers inspire students to use a variety of sensory learning in different problem designs, so that the teaching process is in a positive and enterprising state, which not only enables students to master knowledge, but also cultivates students' thinking and reasoning ability, laying the foundation for students to think with their brains, think in various directions and learn actively, which meets the needs of implementing quality education.
Formulaic calculation of questions
Sixth, the class summary
What did you learn today? What have you gained? What new skills have you mastered? This not only consolidates the knowledge of this class, but also broadens the students' horizons.
20 17 primary school mathematics teaching and research records (2) activity time:
Venue: conference room
Subject: Interpretation of Teacher Wu Yaping's "Basic Course Types of Primary School Mathematics Teaching Structure"
Personnel: all math teachers
Meeting contents:
1. Interpret the types of basic courses of mathematics teaching structure in primary schools in Wu Yaping, and the relevant contents are as follows:
Teaching structure: in short, it refers to different teaching contents, which can form different teaching types according to their internal structure and characteristics. Mathematics teaching in primary schools mainly involves digital cognition, digital operation, law exploration, graphic measurement, concept formation, knowledge arrangement and review.
Teaching structure of digital operation: understand the educational value of digital operation, understand the long-term progressive goal design of digital operation teaching, and pay attention to the integrity of structural learning.
The general goal of number operation: students should know the significance, basic laws and relations of various operations; Be able to judge according to the specific situation and choose the appropriate method for flexible calculation; Be able to use the estimation method flexibly according to the situation and accurately judge the range of calculation results; Can arrange the formulas in an orderly way and find out the rules; Establish basic mathematical sensitivity.
The change of value orientation of digital operation education. New basic education? It is believed that the operation of numbers can not only enable students to master various operation methods and form relevant practical application ability, but also enable students to learn orderly and structured thinking and develop orderly thinking habits. On this basis, they can learn to discover the general laws in mathematical formulas and operations with a unique eye, so as to understand the methods and basic ideas of mathematical discovery, learn to choose the appropriate methods according to the specific situation, and carry out flexible calculations, thus establishing a conscious sense of judgment and choice.
Teachers discuss. Teachers feel a little profound and difficult to understand Mr. Wu's point of view, and need more cases to match their own understanding.
