This is my own! If you can't get angry, everyone is really good at math, and my girl also uses it. Many parents use it for their children, and it is widely praised. I have observed that the learning method and content of this APP are skillfully integrated into the game activities that children are interested in. With the help of graphics and objects, the situation needed for children's cognitive construction is formed, and children's logical thinking is inspired, so that children can take the initiative to learn, bid farewell to traditional cramming teaching, and truly understand the knowledge content, thus achieving the goal of effectively learning mathematics. My girl feels good.
