The following is a simple example of the elementary school mathematics teaching plan for different knowledge points:
** One, two digit multiplied by two digit lesson plan (Part)**
1. ** Teaching goal **
- Let the students experience the process of multiplying two-digit numbers by a whole ten (without rounding) and multiplying a whole ten by a whole ten.
- Able to use mental arithmetic to solve practical problems in specific situations and feel the connection between mathematics and life.
- Cultivate students 'independent exploration, cooperation and communication awareness, obtain successful experience, and establish confidence in learning mathematics well.
2. ** Teaching Focus **
- Understand and master the mental arithmetic method of multiplying two digits by ten.
3. ** Teaching Difficulties **
- Choose different estimation methods to solve practical problems in specific situations, and develop mathematical thinking ability and problem solving ability.
4. ** Teaching process **
- ** Conversation Introduction **
- Do simple two-digit multiplication by one-digit mental arithmetic exercises, such as 1×10, 3×32, etc., and ask the students to say the calculation method.
- This leads to the content of the two-digit multiplication of ten that we are going to explore in this lesson.
- ** Exchange and share **
- ** Teaching example 1**
- Show example 1 on page 1 of the textbook to guide the students to obtain mathematical information from the situation map and think about how to solve the 10 boxes.
- Exploring the algorithm, such as calculating 9 boxes first and then adding 1 box (12×9 = 108, 108+12 = 120), calculating 2 boxes first and then calculating 5 boxes (12×2 = 24, 24×5 = 120), etc. After comparison, the students were guided to understand the simplicity of adding a 0 directly after 12.
- Complete the "try" and summarize the mental calculation method of multiplying two digits by ten (multiply a number by ten and add a zero to the end of the number to get the product) and the mental calculation method of multiplying a whole ten by a whole ten (multiply the number before zero and add two zeros to the end of the product).
- ** Teaching example 2**
- Show the textbook to the students and let them read out the data on the table. Think and speak according to the results. Guide the students to find the characteristics of each bag of garlic.
** II. A simplified lesson plan for division with remainder (Part)**
1. ** Teaching goal **
- To help students understand the meaning of division with remainder and grasp the calculation method.
- Make the students master the method of quotient test and understand the truth that the remainder is smaller than the division.
- Cultivate the students 'preliminary observation and summary abilities.
2. ** Teaching Focus **
- There was a calculation method for remainder division.
3. ** Teaching Difficulties **
- Test business.
4. ** Teaching process **
- ** Foreshadowing and nurturing **
- Practice the "What is the largest number that can be filled in ()", such as 3×()<22, etc., and think about how to fill it in.
- Use the vertical formula to calculate the division. Ask the students to recite the calculation process and the names of each part.
- ** Exploring new knowledge **
- ** Teaching example 1 (6/3 = 2)**
- The students were guided to replace the pears with round pieces and the small sticks instead of plates. The six pears were placed on three plates on average and calculated in a row.
- Ask the students to verbally explain the meaning of each number in the column, including the dividends, divisions, quotient, products, and the 0 that indicates that there is no remaining after the division.
- ** Teaching example 1 (7/3)**
- Let the students follow the previous method and observe the situation of putting 7 pears on 3 plates.
- The teacher inspired and guided the students. The students demonstrated and answered questions, such as how to divide, whether to divide, how many plates were divided, and how many plates were left.
- The teacher explained the writing method of the vertical form by analogy, including the number divided, the number divided evenly, the position of the quotient, the position of the number divided, the position of the remainder, etc., emphasizing the concept of the remainder and leading to the topic of division with the remainder.
- Comparing the similarities and differences between general division and division with remainder.
** 3rd Grade, First Volume, Counting (Part)**
1. ** Teaching goal **
- [Knowledge and Ability Target] Through counting activities, students will learn how to count objects within 10, and verbally express the number of corresponding objects with numbers from 1 to 10.
