Elementary school students 'mathematics problem solving skills
The following are some elementary school math problem solving techniques: 1. Drawing Strategy: Translate the words of a difficult problem into a picture. It can quickly sort out your thoughts and find a solution. In the process of solving a problem, by drawing a diagram related to the meaning of the problem, the diagram was used to help reasoning and thinking. This was especially common when solving problems such as geometry, proportions, or scores. 2. ** Transformation Strategy **: Transform a complex problem into a simple problem, and turn an unknown problem into a known problem. This is one of the common methods used to solve problems in primary school mathematics. 3. ** List Strategy (Enumeration Strategy)**: List the condition information of the problem in the form of a table. This makes it easy to find the problem and analyze the quantitative relationship, thereby eliminating the interference of non-mathematical information. At the same time, it also helps to find a solution to the problem. When using it, one must pay attention to not repeating or missing anything. 4. ** Enumeration Strategy **: When solving some special problems that cannot be calculated, it can list all possible situations of the research object, so that the problem can be solved more easily. When listing, you have to think in an orderly manner to ensure that you don't miss anything. 5. ** Substitution Strategy **: Used to solve the problem of the relationship between several quantities and the total quantity. By using this strategy, the relationship between two quantities could be simplified into one, which would help to solve the problem. 6. ** Comparing Method **: According to the meaning of the mathematics question, compare the meaning and essence of concepts, properties, laws, rules, formulas, terms, and terms. Relying on the understanding, memory, recognition, reproduction, and transfer of mathematical knowledge to solve the question. This would help train the child to have a correct understanding of mathematics knowledge, a firm memory, and accurate identification. 7. ** Comparisons **: By comparing the similarities and differences of mathematical conditions and problems, you can study the reasons for the similarities and differences and find a solution to the problem. When using it, you need to pay attention to the completeness of the comparison, find the connection and difference, compare under the same relationship, and grasp the main content to compare carefully. 8. Formula Method: Use laws, formulas, rules, and rules to solve problems, reflecting deductive thinking from the general to the special. However, it was necessary to ensure that the child had a correct and profound understanding of formulas, laws, rules, and rules, and could use them accurately. 9. ** Analysis Method **: To break down the whole into parts, to break down complex things into various parts or elements, and to study and derive these parts or elements. The idea was to start from the problem to be solved, choose the two conditions needed correctly, and deduce them one by one until the problem was solved, which was "tracing the cause from the effect." 10. ** Holistic approach **: For some calculations, when a certain part cannot be calculated directly, this part can be regarded as a whole and solved step by step. For example, when solving an equation, if there were multiple calculation steps on one side of the equal sign and a certain part could not be calculated, one could first treat this part as a whole to solve it. 11. ** Using Aptitudes **: When you encounter complex calculation problems, you can use approximate numbers to help with quick calculations. 12. ** logical reasoning method **: When solving some reasoning or logic questions, use logical reasoning to get the correct answer. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>

Elementary School Mathematics Square Matrix Problem-solving Skills and Methods
The square matrix problem was divided into a solid square matrix and an empty square matrix. The following were the techniques and methods to solve the problem: ** 1. The relationship between the number of people on each side and the number of people around the square matrix ** 1. ** Knowing the number of people on each side, please ask for the number of people in four weeks ** - Number of people around =(number of people on each side- 1)×4. For example, if there were five people on each side, the number of people around =(5 - 1)×4 = 16 people. This was because the people at the four corners of the square matrix would be counted again, so they had to subtract 1 and multiply by 4. 2. ** Knowing the number of people around, please ask for the number of people on each side ** - The number of people on each side = the number of people in all four weeks divided by 4+1. For example, if there were 20 people in a square formation, the number of people on each side =20 div4 + 1=6 people. ** 2. Calculating the total number of people in the square matrix ** 1. ** Solid Square Matrix ** - Total number of people = number of people on each side x number of people on each side. For example, if there were six people on each side, the total number of people =6×6 = 36 people. 2. ** Hollow Square Array ** - ** Method 1: Subtract the small solid square matrix from the large solid square matrix (Hollow Method)** - Total number of people =(number of people outside) × (number of people outside)-(number of people inside) × (number of people inside), where number of people inside = number of people outside-number of floors ×2. For example, a three-layer hollow square array, the outermost layer has 10 people on each side, the number of people on the inner side =10 - 3×2 = 4 people, the total number =10×10 - 4×4 = 84 people. - ** Method 2: Accumulate each level ** - First, find out the number of people on each floor. For every floor in the square matrix, the number of people on each side will decrease by 2. Then, he added up the number of people on each floor. For example, if there were 14 people on each side of the outermost layer, the outermost layer would have 52 people, the second layer would have 12 people on each side, and the third layer would have 10 people on each side. The total number of people would be 52+44+36 = 132. - ** Method 3: Average substitution method ** - The number of people in each layer could be seen as an arithmetic progression with a difference of 8. The total number of people in the hollow square matrix was equal to the number of flower pots in the second layer from the outside (assuming it was the middle layer) x the number of layers. For example, the three-layer hollow square array mentioned above, counting from the outside, the second layer has 12 people on each side, the number of people =(12 - 1)×4 = 44 people, the total number of people =44×3 = 132 people. - ** Method 4: Extending with four blocks ** - If the hollow square matrix was divided into four equal squares, the total number of people =(number of people on each side-number of floors) x number of floors x 4. For example, if there were 14 people on each side of the outermost layer, the total number of people would be (14 - 3)×3×4 = 132 people. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>

The third grade of elementary school uses the method of continuous multiplication to solve the problem of mathematics teaching plan
The following is an example of a third-grade elementary school math lesson plan that uses the multiplication method to solve a problem: ** 1. Teaching objectives ** 1. Students were asked to use the numerical relationship of the continuous multiplication problem to list out comprehensive formulas to solve practical problems through operation and observation in specific problem situations, so as to cultivate the ability to solve practical problems. 2. Students will experience the process of discovering, proposing, analyzing, and solving problems, experience the variety of methods, and cultivate the awareness of observing and thinking about problems from multiple perspectives. 3. Cultivate the students 'basic abstract ability, hands-on practical ability, application awareness, and innovation awareness, and accumulate mathematical activity experience. ** 2. Important and Difficult Points in Teaching ** 1. ** Main point ** - Master step-by-step or comprehensive formulas to solve practical problems related to continuous multiplication. 2. ** Difficulty ** - He tried to think about the problem from different angles and seek different solutions. ** 3. Teaching preparation ** 1. Teacher's preparation: Coursewares, object projector. 2. Students prepare: learning tools, discs, homework papers. ** 4. Teaching process ** #(I) Scenery Introduction 1. ** Create a scenario ** - Show the picture in the information window 1 on page 40 of the textbook (for example, the picture of the green ecological park). Ask: Students, have you been to the green ecological park? Today, I'll take you to take a look. 2. ** Introduction ** - He guided the students to observe the blooming flowers and pointed out the mathematical problems in today's class to explore the green ecological garden. This scene could stimulate the students 'interest in exploring. #(II) Exploring new knowledge 1. ** Observe the scene map, find mathematical information, and ask questions ** - The teacher pointed out that there were pink, yellow, red, and other colors of flowers in the picture, and there were equally many flowers of all three colors, and asked what "equally many" meant (the same number and the same arrangement). - The students were guided to carefully observe the hidden mathematical information in the picture. For example, there were five rows of each color and eight pots in each row. - Based on this information, the students were guided to ask mathematical questions, such as "How many pots of flowers are there in total?" The class also showed the complete examples and asked the students to read the questions. 2. ** Independent analysis, problem solving ** - How many pots of flowers are there in total? This question was used as an example for teaching. - ** Intuitional operation, understanding the relationship between numbers ** - In order to facilitate the analysis, the students were asked to replace the flowers with small round pieces. The three groups of small round pieces represented the flowers of three colors. The students were guided to determine what to calculate first and then what to calculate on the basis of hands-on operation. - ** Exchange and discuss, show the algorithm ** - Invite the students who have the answers to come on stage and use the hands-on process to explain their thoughts. - ** Step-by-step answers ** - First, calculate how many pots there are for each color. The formula is: 5×8 = 40 pots. This step was to multiply the number of pots in each row by the number of rows to obtain the number of pots of a color. - Then, he calculated the total number of pots of flowers of the three colors. The formula was: 40×3 = 120 (pots). This was the total number of pots obtained by multiplying the number of pots of flowers of a color by the type of color. - ** Comprehensive Formula ** - The general formula was: 5×8×3 = 40×3 = 120 (pots). Here, the product of 5×8 was calculated from left to right, then multiplied by 3. - Students could also be guided to think from another perspective. First, find out how many pots there were in a row of flowers of three colors. The formula was: 8×3 = 24 (pots). Then, calculate how many pots there were in total. The formula was: 24×5 = 120 (pots). The comprehensive formula was: 8×3×5 = 24×5 = 120 (pots). #(3) Consolidating Practice 1. For example, in the stamp album, there were three rows of stamps on each page, and each row had four stamps. How many stamps were there in total on the three pages? Let the students do it independently and exchange ideas. 2. The students were given information such as 4 yuan for each shuttlecock and 6 shuttlecocks in a box. #(IV) Class summary 1. Guide the students to review what they learned today, that is, how to solve problems with continuous multiplication. 2. He emphasized that he could make better use of successive multiplication to solve problems in life. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
