There are obvious age differences in children's classification ability. When they are in large classes, they can not only classify objects according to the external characteristics of colors and shapes, but also start to classify them according to their uses.
We can do several small surveys: one is to judge according to the negative or positive standard of one feature of an object, the other is to judge according to two features of an object, and the third is to classify from multiple angles.
The specific training methods are as follows:
Split the screen game first. Prepare common items, plants, vehicles, daily necessities and other items or pictures for children to play games.
Second, organize the items. At home, let the children organize their toys, books, clothes and schoolbags and classify the items. You can ask children questions at multiple levels and angles, and follow the principle of easy before difficult in the process of playing, and guide children to observe carefully. Classification from paying too much attention to the appearance of things to going deep into the essence.
In addition to classification ability, sorting is also a particularly important ability. Sorting refers to the orderly arrangement of a group of objects according to some characteristic difference or some rule. According to Piaget's theory, sorting is a very important logical ability, which depends on the development of children's sequence structure. Children's thinking is reversible, transitive and dual, thus constantly comparing the differences of objects.
In daily life, children can use the items in their lives to sort by size, number, height, length, thickness, color, weight, distance or other rules.
