In recent morning activities, children especially like to arrange flowers, string beads and wear necklaces. Through children's conversation and communication, I learned that children have a correct perception of the arrangement law, but they have insufficient cognition of the arrangement law. Therefore, I designed this activity according to the problems recently discovered in our class. I want to let children have a correct understanding of regular sorting through this activity, and let children sort according to the arrangement of graphics.

Teaching reflection

This activity, sorted by law, aims to train children to use what they have learned flexibly to solve problems. The whole activity is based on the main line of receiving gifts. It is divided into three parts with distinct levels. In the first part, children can observe and find that the graphic queue is regular. Through graphic comparison, guide children to perceive the basic characteristics of graphic queuing. This is the training of children's preliminary judgment and reasoning ability. In the second link, children can use heuristic and prompt methods to guide children to further master and summarize the arrangement characteristics of graphics on the basis of discovering laws. Let children feel the pleasure of sorting different colors and different graphics according to the law, and also exercise their observation and agility.

During the activity, some operating materials with different difficulties were set up to meet the needs of different children.
