"Simple Cycle" is a micro-course provided by Garden Township Central School. The speaker is Zheng Xianghua.

"Simple cycle" is a special practical activity in the first volume of the fourth grade textbook of the New Soviet Education Press. It is not difficult to find the law in this lesson. The key point is to find the law and solve the problem by division.

Examples of this lesson choose familiar things around students, such as "potted flowers, colorful flags, colored lights", so that students can feel the connection between mathematics and life, focus on the observation of different object arrangements, and stimulate great learning enthusiasm and interest.

Design concept:

I first introduce questions by playing games to guide students to discover the hidden mathematical factors in life and perceive the "law". By drawing a picture and arranging it in a line, determine the color and shape of the object in a certain position. For a large number of objects, the calculation of discovery column is to determine the color and shape of an object in a position by knowing whether there is a remainder.
