How to write a PPM analysis of primary school mathematics questions

Answer 1

The following are the general steps for writing a PSP analysis of primary school mathematics questions:

** I. Overall Planning **

1. ** Clear target **
- Decide if the powerpoint analysis is a review of a specific knowledge section (such as calculations, graphics, etc.) or a comprehensive review. If it was to help students cope with the primary school entrance examination, it had to cover the key content in the examination outline.
2. ** Construction design **
- ** Cover **: The title of the powerpoint, such as "Elementary Math Problem Analysis", and a sub-title (if any). You can add your name or the production date (if applicable).
- ** Table of contents page **: List the types of questions or knowledge points to be analyzed, such as the understanding of numbers, the four arithmetic operations, the calculation of the area of the graph, etc., to provide navigation for the PSP content.
- ** Main content page **: This is the core part, analyzing all kinds of questions in detail.
- ** summary page **: summarize the key content, emphasizing the key ideas and methods of solving the problem.
- ** Back cover **: You can write some thanks or contact information (if necessary).

** 2. Fill in the content **

1. ** Knowledge Points Sorting (Concept Sorting)**
- The mathematical concepts related to each question type were briefly explained. For example, when analyzing a score question, one had to explain the definition of a score (dividing the unit "1" into several parts, indicating that such a number or several parts were called scores), the composition of the score (numerator, decimal, score line), and so on.
- Diagrams and examples can be used to help understand concepts. For example, a circle could be divided into several parts, and several parts could be expressed as scores.
2. ** Question presentation and analysis **
- ** Question Selection **
- He chose representative questions, including basic questions, error-prone questions, typical comprehensive questions, and so on. For example, in the Four Arithmetic Section, one could choose a simple addition formula such as 2+3, or one could choose an error-prone mixed calculation question such as 3+(4 - 2)×5.
- The source of the questions could be teaching materials, practice question sets, or real exam questions from previous years.
- ** Steps to solve the problem **
- For each question, the steps to solve it were shown in detail. Take the question of the distribution law of multiplication as an example. For example, 3×(2 + 5), you have to write down the calculation process of 3×2+3×5 and explain the basis of each step (the distribution law of multiplication: a×(b + c)=a×b + a×c).
- When displaying the steps, you can use animation effects to gradually show the calculation process and enhance the demonstration effect.
- ** Analysis of errors (error-prone questions)**
- He pointed out the areas where mistakes were easy to make. For example, when calculating division, students would easily forget to convert the quotient into an integral number and expand the dividends by the same multiple when the quotient was a decimal number.
- The reason for the analysis error could be unclear concepts, careless calculations, or wrong solution methods.
- ** Multiple solutions (if available)**
- For some questions, they would show different solutions. For example, when calculating the area of a graph, a quadrilateral could be calculated using the base x height method, or it could be divided into a triangle and a rectangular to calculate the area and then sum.
3. ** Problem solving skills and rules summary **
- After analyzing a class of questions, he would summarize the techniques and rules of solving them. For example, when doing the four mixed operations, multiply and divide first, then add and subtract, and if there are parenthesis, calculate the parenthesis first. When calculating the perimeter of a graph, remember the common perimeter formula of the graph and accurately substitute the data.
- One could use mnemonic formulas, doggerel, and other forms to help students memorize, such as "The four operations have an order, multiplication, division, addition, and addition must be distinguished, and the parenthesis should be calculated first. Don't be careless and make mistakes."

** 3. Visual Design **

1. ** Color matching **
- Choose a simple and harmonious color scheme. For example, the background color could be light blue or white, the text color could be black or dark gray, and the key content could be highlighted in a striking color (such as red).
2. ** font selection **
- Choose clear and easy to read font, such as Song, bold, etc. The font of the title could be slightly larger, and the font of the main content could be moderate to ensure that it could be clearly displayed on different devices.
3. ** The layout is reasonable **
- The layout of each page should be concise and clear to avoid overcrowding the information. Diagrams, words, calculations, etc. must be properly spaced for easy viewing.
4. ** Use of pictures and charts **
- Add a picture or a self-made chart related to the question. For example, when analyzing geometric problems, the corresponding graphic pictures were inserted; when explaining data statistics, the data relationship was displayed using bar charts and line charts.

** 4. Proofreading and Review **

1. ** Proofreading content **
- Check if the mathematical concepts, steps, and answers are correct.
- Confirm that the words are fluent and professional.
2. ** Form Review **
- He checked whether the layout of the PowerPoint was neat, whether the font and color were uniform, and whether the animation effects were reasonable.
