(1) This activity class is designed according to the age characteristics of our children and their acceptance of new knowledge. Because the children in our class haven't practiced books, I design my homework in the form of physical operation to make the children operate better. The children are very interested and they are willing to participate.

(2) In this activity, I created a relaxed and free learning atmosphere for the children in the form of games. Children have no constraints and learn more actively.

(3) From the child's operation, the child can clearly distinguish the three colors of red, yellow and blue, and can classify the items as required.

(4) The disadvantage is that in group games, when I asked my children to send snowflakes home, I asked them to send snowflakes home in the form of freedom, with no special emphasis on discipline. So classroom discipline seems a bit messy. I should let the children line up in batches and then send the toys home, so that the classroom discipline will not be chaotic.
