1 classified memory method
According to the nature, characteristics and internal relations of memory materials, it helps students to remember a lot of knowledge. For example, after learning the unit of measurement, everything you have learned can be summarized into five categories: length units; Area unit; Volume and unit of volume; Weight unit; Time unit. This classification can easily systematize, organize and memorize complex things.
2 Song formula mnemonic method
It is to compile the mathematical knowledge to be memorized into songs, formulas or jingles for easy memorization. For example, to measure the angle, you can compose several songs: "Put the protractor on the angle, with the center aligned with the vertex, with the zero line facing one side and the other side looking at the degree." For another example, the movement of the decimal point position leads to the change of the number size. "Please follow me with the decimal point, and be sure to find' left' and' right' before you go; The horizontal belt is a you, it expands to you; Add a left horizontally and narrow it to the left; Take one step ten times, take two steps a hundred times, and the number of times is not enough to find a' 0' hook. " In this way, students not only like to remember, but also remember well.
3 regular memory method.
That is, according to the internal relations of things, find out the regular things to remember. For example, memory length unit, area unit, unit of volume transformation method and aggregation method. Chemical method and polymerization method are reciprocal, that is, high-level unit value × rate = low-level unit value, and low-level unit value/rate = high-level unit value. Mastering these two laws will solve the problem of chemical polymerization. Regular memory requires students to process and sort out the relevant materials they have learned with their brains, so the memory is firm.
4 list memory method
It is to list some confusing memory materials into tables to achieve the purpose of memory. This method is obvious, intuitive and comparative. For example, to remember the differences between the three concepts of prime number, prime factor and coprime number, you can make a table to help students remember.
5-key memory method
With the growth of age, students learn more and more mathematical knowledge, so it is a waste of time and a bad memory effect for students to remember comprehensively. Therefore, in order to make students learn to remember the key contents, students can remember other contents through deduction and association on the basis of remembering the key contents. For example, learn the common quantitative relationship: work efficiency × working time = workload. Workload ÷ work efficiency = working hours; Workload+working hours = working efficiency. As long as you remember the first quantitative relationship, you can deduce the last two quantitative relationships according to the multiplication and division relationship. This way of memory reduces students' memory burden and improves memory efficiency.
6 associative memory method
It is to remember by thinking about another thing associated with something familiar.
