Three-year-olds like toys best. In fact, this is a good learning opportunity. Expert advice: let children clean up their toys after each play. At this time, children can be asked to classify toys according to their uses, put toys belonging to cars together, put building blocks together and put dolls together. Children will do these things with great interest. After a period of training, it will increase the difficulty. For example, put the car toys on one side and the building blocks on the other side ... so that children will learn to classify in mathematics and know the color content unconsciously. Teaching mathematics with regional activities, people's every move in life is affecting children. Three-year-olds like to imitate the actions of adults best. Therefore, the regional activities of kindergartens provide them with room for imitation. Using regional activities in mathematics teaching can get twice the result with half the effort. Expert advice: play doll's family game. Its function satisfies children's imitation psychology and makes them feel the activities of adults. It is also a good opportunity for children to learn mathematics. Therefore, children can ask questions before playing in the dollhouse. For example, there are several guests at home (learn to count by hand and mouth), and prepare a cup of tea for each guest (one pair). If you invite guests to dinner, you should also prepare a bowl, a spoon and so on for each guest. Through these activities, children can learn to count (the number should be controlled within 5). One-on-one pairing and other mathematical knowledge. After-school games teach mathematics, and mathematical knowledge in real life is everywhere. Similarly, learning mathematics can be carried out in outdoor activities. Experts suggest that when you are outdoors, you can compare with tall and short children. After comparison, children will soon take the initiative to queue from short to high, which can kill two birds with one stone. Children should not only learn to grow taller, but also learn to queue. Teaching mathematics in games. Three-year-olds like building blocks best. Building blocks are not only hands-on, but also brains. Using the time of playing with building blocks, children can be taught to know graphics.
