Let's define the approximate age range of kindergarten children. I think 3~5 years old is a more suitable range. The national compulsory education law stipulates that you can go to primary school at the age of 6, and "those who do not have the conditions" can be postponed to the age of 7. Coincidentally, in the subdivision method of developmental psychology, 3~5 years old is classified as "preschool period". What about children at this stage? Their brains and brains are still developing very fast, but their bodies are also undergoing major changes: the proportion of body fat is declining, the limbs are developing faster than the trunk, and the proportion of head in the body is also beginning to decline. In short-at this stage, our children have changed from babies to brats.
For children, imagination is the transformation of the physical world in the psychological world. This magical psychological operation directly opens a door for children. In that door, there is a social exploration of "playing house", a whimsy of "children's words are not clear", a deep fear of "tiger grandma" and a first attempt at lies. So don't care too much about grades, first cultivate children's interest in learning.
