To cultivate children's habit of saving, we should start from small things and parents themselves: first, explain the significance of saving electricity, a drop of water, a piece of paper and a grain to children. As the saying goes: "A drop of water is not too much, a drop of water becomes a river; One grain of rice is not too much, one grain is piled in a pile. "Let the children know that saving is like swallowing mud, and wasting is like a river that breaks its banks. This is a crime. If you don't form the habit of thrift from childhood, you will harm society, your parents and yourself in the future. Second, parents should set an example. Parents are the best teachers and should set an example. Turn off the tap after running out of water, and don't let the water flow away in vain; Check and repair the faucet frequently to prevent dripping; Use more water, such as washing vegetables and rice, flushing toilets and watering flowers; Wash clothes with phosphorus-free washing powder to reduce water pollution. If you leave the washing water to the next batch of clothes, you can save 30 ~ 40 liters of water each time; Use detergent with caution or less. Third, educate children to save money from small things. Parents should let their children exercise in practice and be strict with small things. For example, girls can't be too demanding in dressing up and can't spend money indiscriminately; Cherish utensils and toys; Save every grain, every drop of water, every kilowatt hour, every piece of paper, etc. Fourth, work closely with schools to educate children to be frugal. Parents should work closely with schools to cultivate children's good habits of thrift. Whether children go to kindergarten, primary school or middle school, they should keep in touch with the school, communicate information and cooperate closely to jointly do a good job in the education of children's diligence and thrift. Children should be educated to save every grain at ordinary times. As the saying goes, "Who knows that every grain tastes bad? "Developing the habit of saving will not only make children more sensible, but also help their future career. Therefore, parents should set a good example for their children and cultivate their children's good habits of thrift from an early age.
