There is a way to build a chain of ideas and trace its origin

——Analysis algorithm

CHEN Xiumei  （Jinguang primary school，Quanzhou City，Fujian Province，china）

【Abstract】The algorithm is a kind of calculation program which has been induced and formed a pattern，and it is to solve the problem of "how to calculate". Calculation principle is the mathematical principle to explain "why to calculate like this"，it is the mathematical basis of the algorithm，shows the whole idea of solving problems，points out the direction for students to form operable calculation，and is the guarantee for the formation and improvement of students' computing ability.

【Keywords】Practical operation;Intuitive calculation;Combination of number and shape;Internalization calculation;Experience transformation
