Large classes should formally learn knowledge, so the corner can be set as follows: the language area "contains pictures of various literacy cards, a news edition, good news selected every day for children to see, and maps for children to understand." In the math area, there are all kinds of objects for children to operate points, as well as all kinds of digital cards, calculation cards, =-+pictures, game areas and toys. Music area "all kinds of musical instruments, children's songs." The science area "grows some plants and raises some creatures." Set up a news corner and choose a theme paper-cut every week to let the children know.
