Need to buy hand scissors and glue with appropriate size, plasticine with reasonable price and appropriate hardness, and a certain amount of electro-optic paper for children. But a larger amount needs to be accumulated slowly at ordinary times and used as waste. It is more economical to collect sticky loess or black soil and add a proper amount of water to make mud than to buy ready-made plasticine. After each use, you can make a ball, dig a hole in the ball, and fill the hole with water, so as not to let the ball crack and find no soil. You can add water and salt to the dough to make them. Prepare papers of various textures and sizes, which can be "waste paper" used and written by parents; String, yarn, rags, leaves, colored paper, wrapping paper, cigarette case paper, matchbox, bottle cap, cork, old toothbrush, even pencil scraps, broken pen caps, etc. , are rarely used "treasure".
Parents should encourage their children to accumulate together, so that he will cherish the materials. And there must be a fixed container to hold it, usually packed up and put it in a fixed place.
