Elementary school Olympiad math figure arrangement filling number skill teaching plan
** 1. Teaching objectives ** 1. Let the students understand the concept of the number matrix. Through the practice of arranging the numbers, the students 'observation ability and logical thinking ability will be cultivated. 2. Guide the students to master the basic skills of arranging and filling in numbers, including finding key numbers and discovering the pattern of numbers. 3. To stimulate the students 'interest in the relationship between figures and numbers in Mathematical Olympiad, and to improve the students' confidence in solving such problems. ** 2. Important and Difficult Points in Teaching ** 1. ** Teaching Focus ** - Master the method of finding rules from the sum, difference, product, quotient relationship of adjacent numbers and the relationship between interval numbers. - Learn to analyze the arrangement of numbers in the array and find the key numbers. 2. ** Teaching Difficulties ** - How to accurately discover the hidden patterns between the numbers in a more complicated array diagram? - Using various techniques to solve different types of problems. ** 3. Teaching Method ** Teaching method, discussion method, and practice method were combined. ** 4. Teaching process ** 1. ** import (5 minutes)** - It was about the story of Jingjing and Yingying in the Snow Elf Kingdom in Math Paradise. It led to the problem of filling the seven numbers 1 - 7 on the seven petals of the snowflake so that the sum of the numbers on every three petals on the same line was equal. To stimulate the students 'interest in the game, let the students have a preliminary understanding of the number array. 2. ** Knowledge explanation (15 minutes)** - ** Basic Skill 1: Analyzing the relationship between adjacent numbers ** - Take the sequence as an example, if you fill in the numbers according to the rules: 2, 1, 4, 1, 6, 1,( ),( ). He guided the students to observe and found that the odd terms were 2, 4, and 6, which was the law of increasing by 2 in turn, while the even terms were all 1. Therefore, 8 and 1 should be written in the parenthesis. - Another example is 3, 2, 9, 2, 27, 2,( ),( ). Here, the odd numbers are 3, 9, and 27, and the latter number is three times the previous number; the even numbers are all 2. Therefore, 81 and 2 should be written in the parenthesis. - ** Basic Skill 2: Analyzing the relationship between numbers ** - Give a sequence of numbers such as 18, 3, 15, 4, 12, 5,( ),( ). The students were guided to split the sequence into odd terms 18, 15, and 12, which was the rule of decreasing 3 in turn, and even terms 3, 4, and 5, which was the rule of increasing 1 in turn. Therefore, 9 and 6 should be written in the parenthesis. - For 1,15,3,13,5,11,( ),( ), the odd terms 1,3,5 are the law of adding 2 in turn; the even terms 15,13,11 are the law of decreasing 2 in turn. Therefore, 7 and 9 should be written in the parenthesis. - ** The key number in the array map ** - Using a simple triangular array as an example, the numbers on the three corners had a certain relationship with the number in the middle. For example, the number in the middle was equal to the sum of the numbers on the three corners. Starting from a number array with a complete set of known numbers, the students were guided to analyze the rules and find the key numbers (the numbers on the corners or the middle numbers) to determine the numbers in other positions. 3. ** Practice and consolidate (20 minutes)** - He gave some practice questions about the number matrix and the number sequence, such as: - Count the number of triangulations in the following picture (It involves the relationship between the number of numbers and the number of triangulations in the triangular array). - Find the pattern and fill in the numbers: 4, 7, 8, 4, 6, 13, 4, 5, 18,( ),( ),( ). - There was a numerical array diagram that showed some numbers. Students could find the pattern according to the skills they had learned and fill in other numbers. - Students were allowed to complete the exercises independently. Teachers would patrol and guide the students, and if they found any problems, they would correct them in time. 4. ** Class summary (5 minutes)** - Guide the students to review what they have learned in this lesson, including the relationship between adjacent numbers, the method of finding the relationship between numbers, and the analysis of the key numbers in the number matrix. - He emphasized that when solving the problem of arranging numbers, he had to observe carefully, think from many aspects, and try different methods to find the arrangement law of numbers. ** 5. Extension of Teaching ** He assigned homework to the students to complete some more complicated questions such as filling in numbers on a number matrix and finding the law of a number sequence to further consolidate the knowledge they had learned.
