The book Let Children Learn Mathematics through Questions focuses on how to lead children's mathematics learning through questions. "Learning begins with thinking, and thinking begins with doubt". Doubt is most likely to cause exploration and reflection, and thinking is generated from it. With questions, doubts and surprises, children can think positively. The process of problem guiding children to learn is the process of finding, solving and producing problems. An interesting and valuable "question string" goes from shallow to deep, encouraging children to think deeply. Interlocking problems extend thinking from the outside to the inside. Correct "question string" causes children's cognitive conflict and breaks children's cognitive balance. The throwing of questions and the repeated climax of thinking arouse the ripples of thinking, and build the temperature of the classroom on the depth of thinking, so that children are in a state of wanting to pull away, immersed in the atmosphere of independent exploration, and feel the fun and value of learning mathematics. When you have a question, you will think "Don't be angry, don't worry, don't send it", which will cause children to think and make them actively explore.
