Elementary school third grade mathematics Beijing Normal University edition test questions
The following are some examples of the third-year mathematics test questions: ** 1. Fill in the blanks ** 1. If you want to make the product into a three-digit number, you can fill in 5 at most. The product of 21×93 is about 1800 (take 21 as 20, 93 as 90, 20×90 = 1800). 40×70 is 28 100 (40×70 = 2800, 2800 × 28 = 100). 2. If one observed a four-sided body from different angles, they could only see three faces at a time. 3. Using the 24-hour clock system, 4:00 p.m. was 16:00 p.m.(4 + 12 = 16), 8:00 a.m. was 8:00 p.m., and 12:00 p.m. was 24:00 p.m., which was also 0:00 p.m. on the second day. 4. 48 months =4 years (48/12 = 4), 800 square meters =8 square meters (800/100 = 8). 5. A desk in the school cost 150 yuan, which was three times the price of a chair. A chair cost 50 yuan (150 × 3 = 50). ** 2. Area related issues ** 1. A square piece of paper was reduced by 3 centimeters on each side, and its area was reduced by 99 square centimeters. How many square centimeters was the original square? - First of all, calculate the area of the reduction after removing a small square with a side length of 3 cm: 99 - 3×3 = 90 square centimeters. This 90 square centimeters is the sum of the area of the remaining two identical rectangular shapes, so the area of a rectangular shape is 90 × 2 = 45 square centimeters. And because the width of this rectangular shape was 3 centimeters, the length was 45 div3 = 15 centimeters. The original square's side length was 15+3 = 18 centimeters, and the original square's area was 18×18 = 324 square centimeters. 2. There is a small square in the big square. The circumference difference between the two squares is 8 cm, and the circumference sum is 40 cm. What is the area of the big square? - Because the difference in the circumference of a square was 8 centimeters, according to the circumference of a square = side length ×4, the difference in side length could be 8 × 4 = 2 centimeters. The sum of the circumference was 40 centimeters, so the sum of the side lengths was 40 div4 = 10 centimeters. If the side length of a small square is x cm, then the side length of a large square is (x + 2) cm. The equation x+(x + 2)=10 can be solved to obtain x = 4 cm, so the side length of a large square is 4+2 = 6 cm, and the area of a large square is 6×6 = 36 square centimeters. ** 3. Usage Questions ** 1. Xiao Ming's house was 250 meters away from the school. He had to walk to and from school twice a day. How many meters did he have to walk in a day? How many kilometers did he walk in a week (calculated in five days)? - One round trip was 250 x 2 = 500 meters, and two round trips were 500 x 2 = 1000 meters. In a week (5 days), he had to walk 1000 x 5 = 5000 meters, 5000 meters = 5 kilometers. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>

Reflection on the teaching of pinecone in the second grade of primary school in Beijing Normal University
The teaching reflection of Counting Pine Cone Fruits could be carried out from the following aspects: * * I. Achievement of teaching objectives ** 1. * * Knowledge and Skills ** - The main point of Counting Pines was to let the students understand the formation process of the multiplication formula. In the teaching, students were guided through a variety of ways to understand the formation of the multiplication formula. For example, through the calculation of the number of pine cones, they gradually transitioned from the addition formula to the multiplication formula. For example, let the students observe the pile of pine cones. There are five pine cones in one pile, and how many pine cones are in two piles (it can be expressed as 5 + 5 = 10, or 2 × 5 = 10), and so on. Gradually construct the multiplication formula of 5. - As for the difficulty of using the multiplication formula to solve practical problems in life, one could create life situation questions, such as calculating how many bags a certain number of pine cones could be packed, and let the students use the formula to answer them to test the students 'mastery and application of knowledge. 2. * * Method and process ** - In the process of teaching, many teachers adopted independent inquiry learning methods, such as inquiring deskmate discussions and group cooperation. It was convenient and fast to communicate with the students at the same table. When the students had mastered a certain method and needed to summarize in time, it was better to let the students summarize. For example, when writing the multiplication formula of 5, the teacher would demonstrate it first, then let the students participate in the form of half-support and half-release. Finally, the students would work together to write the formula. This process of "support" to "release" followed the students 'cognitive law, from concrete to abstract, from perceptual to rational. It allowed the students to actively participate in the whole process of knowledge, and initially cultivated the students' learning ability. - At the same time, there were also teachers who designed a large number of games, such as using passwords when memorizing the pithy formula, picking fruits during practice, etc., which embodied the concept of "learning by doing, learning by playing", so that students would be happy to remember and remember firmly, increasing the fun of learning. 3. * * Emotions, attitudes and values ** - In the entire teaching process, when the students could correctly write the pithy formula and use the pithy formula to solve the problem, they could experience the joy of success and increase their confidence in learning mathematics. Moreover, in the process of group cooperation, it could cultivate the students 'sense of cooperation and team spirit. * * 2. The effectiveness of teaching methods ** 1. * * Intuitional teaching ** - As the second grade students mainly relied on intuitive teaching aids to think, they could use methods such as placing small sticks to let the students understand 1 5, 2 5... and thus understand the meaning of multiplication. For example, students could use small sticks to arrange a pile of pine cones in groups of five. They could understand the multiplication formula and the formula through the intuitive number of small sticks. 2. * * Heuristic Teaching ** - In teaching, the teacher inspires the students to think by asking questions, such as "How many pine cones are there?" How to express it with a multiplication formula? Can you try to make up the rest of the chants?" Wait for the question. These questions were designed with a clear direction, allowing the students to clearly know what to do and how to do it. It not only allowed the students to use their brains to think, but also provided the students with an opportunity to develop their language. * * 3. Inadequacies and improvements in the teaching process ** 1. * * Not enough ** - In the teaching process, there might be some students who did not have a deep understanding of the multiplication formula, especially in terms of memorizing the formula and flexibility in application. For example, students might not be able to quickly and accurately choose the appropriate multiplication formula to calculate when solving some slightly complicated practical problems in life. - There might be problems with individual students 'low participation in the classroom interaction. In group cooperation, some students might rely on other students and lack the awareness of active thinking and active participation. 2. * * Modification ** - More types of exercises could be added to the understanding and application of the pithy formula, including some challenging expansion exercises, such as reverse thinking questions (knowing one factor of the product and finding another factor) to deepen the students 'understanding and application of the multiplication formula. - In order to increase student participation in class, in group cooperation, the tasks and responsibilities of each student could be clearly defined. For example, a group leader could be set up to supervise and encourage each member to participate. At the same time, teachers should pay more attention to students who did not participate much during the inspection process and give timely guidance and encouragement. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>

Teaching Method Discussion - According to the content of the teaching materials and the learning situation, they would discuss suitable teaching methods together. For example, when teaching the volume calculation of a cylinder and a cone, the experimental demonstration method could be used to let the students intuitively feel the derivation process of the volume. When explaining the concept of direct proportion and inverse proportion, the example comparison method could be used to deepen the students 'understanding. - It was to discuss how to use multi-media resources and teaching aids to assist in teaching, such as using animations to demonstrate the formation process of the cylinder's side expansion map to help students understand the calculation of the cylinder's side area. 4. Teaching schedule - According to the requirements of the teaching outline and the difficulty of the teaching content, a detailed teaching schedule was formulated. - At the beginning of the semester, a certain amount of time was arranged to focus on the "cylinder and cone" section to ensure that students grasped the basic geometric concepts and calculation methods. - Then, he gradually introduced the knowledge of " direct and inverse proportions ", reasonably allocated the teaching time for each topic, and arranged appropriate practice and consolidation sessions. - At the end of the semester, they would set aside enough time for a general review, which would be divided into modules for systematic review. For example, they would review the number and algebra section first, then the space and graphics section, and finally the comprehensive simulation exercise. 5. Homework design and evaluation - The design was layered, including basic homework, improvement homework, and expansion homework. The basic homework focused on consolidating the basic knowledge, the improvement homework focused on the comprehensive application of knowledge, and the expansion homework focused on expanding the thinking of students who had the ability to learn. - They discussed how to effectively evaluate homework. In addition to giving right and wrong judgments, they also paid more attention to the feedback of students 'solution ideas and learning attitudes to promote students' enthusiasm for learning. ** 3. Time for preparation ** 1. Every week, there would be a fixed preparation time. For example, every Monday afternoon, all the sixth grade math teachers would participate. 2. Before important teaching nodes, such as before the start of the unit teaching and before the start of the review stage, increase the number of times to ensure the smooth implementation of the teaching plan. ** IV. Sharing and implementation of the collected results ** 1. The collected results were compiled into detailed teaching guidance documents, including lesson plan examples, teaching coursewares, homework designs, etc., which were shared with each teacher. 2. Teachers should flexibly use the collection and preparation results according to the actual teaching situation in the teaching process, and timely feedback the problems encountered in the implementation process, so as to further adjust and improve the collection and preparation plan. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
Elementary school fourth grade first volume western normal university edition mathematics question
The following is some of the content related to the fourth grade mathematics questions: ** 1. Unit Conversion ** 1. ** Conversion of length units ** - For example, how many decimeters was 3 meters? According to 1 meter = 10 decimeters, 3 meters = 3×10 = 30 decimeters. - How many meters was 500 centimeters? Since 1 meter was equal to 100 centimeters, 500 centimeters was equal to 500 divided by 100 = 5 meters. 2. ** Area Unit Conversion ** - How many square decimeters was 2 square meters? 1 square meter = 100 square meters, 2 square meters = 2×100 = 200 square meters. - How many square meters is 30000 square centimeters? Since 1 square meter = 10000 square centimeters, 30000 square centimeters = 30000 divided by 10000 = 3 square meters. ** 2. The classification of angles and related calculations ** 1. ** The degree of the angle is determined ** - Give the degree of an angle and determine what angle it is. For example, an angle of 35° was an acute angle because it was greater than 0° and less than 90°. - For an angle of 120°, since it was greater than 90° and smaller than 180°, it was an obtuse angle. 2. * * Calculating the relationship between the number of horns ** - Given a circular angle, how many right angles is it equal to? Because 1 circle angle = 360°, 1 right angle = 90°, so 1 circle angle = 360° × 90° = 4 right angles. ** 3. Relationship between quantity (unit price, quantity, total price; speed, time, distance)** 1. ** Relationship between unit price, quantity and total price ** - Knowing that the unit price is 5 yuan, the quantity is 8 pieces, asking for the total price. According to the unit price x quantity = total price, the total price = 5 x 8 = 40 yuan. - If the total price is 60 yuan and the unit price is 10 yuan, ask for the quantity. From the total price divided by the unit price = the quantity, it can be seen that the quantity = 60 divided by 10 = 6. 2. ** Speed, Time, Distance Relationship ** - Speed: 12 m/s, Time: 5 seconds, Distance: According to the speed x time = distance, the distance = 12 x 5 = 60 meters. - The distance is 80 kilometers, and the speed is 20 kilometers per hour. From the distance/speed = time, it could be seen that time = 80/20 = 4 hours. ** 4. Rectangle and Square Area Classes ** 1. ** Rectangle Area Calculation ** - Given that the length of the rectangular shape is 8 cm and the width is 5 cm, find the area. According to the area of the rectangular shape = length x width, the area = 8 x 5 = 40 square centimeters. - If the area of the rectangular shape is 48 square meters and the width is 6 meters, find the length. From the length = area/width of the rectangular shape, it could be seen that the length = 48/6 = 8 meters. 2. ** Square Area Calculation ** - The side of a square is 7 decimeters. Find the area. According to the square's area = side length x side length, the area = 7 x 7 = 49 square decimeters. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>

Reflection on the Midterm Teaching of the Second Volume of the Sixth Grade Mathematics in Beijing Normal University
In the second volume of the sixth-grade mathematics semester, there were the following reflections. The teachers found many differences and perplexities in the process of teaching the sixth grade mathematics many times. Although there were innovation and improvements in this semester's teaching, such as grasping the key points to develop the students 'thinking and comprehensive application ability, there were still some problems. 1. [Problem with the progress of underachievers: After investing more time and energy in underachievers, the improvement in their grades will be small, and there will be a gap between their results and expectations.] They forgot knowledge quickly, and soon forgot what they had just been taught. It was difficult to make up for the accumulation of knowledge during comprehensive practice. 2. ** Students 'thinking and application ability problems **: Some students are not good at using their brains to think, drawing inferences from one instance, and passively accepting knowledge. He was not good at using knowledge to solve more complicated application questions, nor did he use line diagrams to help understand the meaning of the questions. 3. ** Study habits ** - ** Calculating Habits **: A small number of students have not developed good calculating habits. - ** Question review habit **: Some students do not review questions carefully, and they are prone to making mistakes in simple questions. - ** Checking Habits **: A small number of students do not check or do not check after they finish the questions. They turn a blind eye to obvious mistakes or are too lazy to check. 4. ** Comprehensiveness of teaching **: There are some inadequacies in the teaching process. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
