1. The teacher in Singapore public primary school wrote a 3 on the blackboard, asking the children to talk about anything related to 3, such as 3 apples, Wednesday, 3 o'clock, 5 - 2 is 3, and so on. Then the teacher summarized it again. In these classes, we can feel the teacher's cultivation and implementation of this divergent and systematic thinking, not criticizing children, but encouraging them to speak out their own ideas.
2. Singapore public primary schools will instill practical social and economic concepts, and even some primary schools start to discuss some very macro concepts from an early age. For example, children in the second grade of primary school discuss the relationship between natural resources, people and the environment in the classroom; Discuss the "system" created by human beings: such as buying and selling; Understand what money is, even if it involves "trade". These macro concepts are actually very practical, and also conducive to improving children's understanding and humanistic feelings.
