Many people think that mathematics is monotonous and abstract and divorced from our lives. It is this kind of thinking that stifles children's interest in learning mathematics. In fact, learning mathematics is a happy thing. As long as you observe it carefully, it is everywhere. From the arrangement of house numbers to the research and development of science and technology, we seem to live in a world full of numbers. First of all, we should help children find interesting math problems around them, let them feel the mystery and fun of math through some interesting math games, and stimulate their passion for learning math and interest in exploring knowledge. When children think that math knowledge can help you solve the problems around you and help you become smarter, learning math will be much easier and happier. Secondly, many children are afraid of making mistakes and think that they will be criticized if they do something wrong, thus losing confidence and feeling inferior. On the contrary, we should encourage mistakes, which come from children, be close to children, expose children's true thinking, and help us find obstacles to children's knowledge construction together. In fact, some mistakes also include children's own creativity. They use their own unique thinking and ideas to solve problems. Through clever teaching and guidance, they can help children break through obstacles and even reach a realm of their own innovation. Let children not be afraid of making mistakes, explore boldly, imagine boldly, untie the framework that imprisons children's thinking, and let children study in a happy and relaxed environment.
