Mathematical language comes from life and is an abstraction of life language, which is used to express quantitative relations and spatial forms. Written language: used to define concepts and reveal essential attributes. Symbolic language: concise, easy to write, and concentrated expression of mathematical content. Graphic language: intuitive expression, helpful to memory, helpful to thinking, and can solve problems visually.
The new series of "Primary School Mathematics" grasps the core concepts of mathematics and discovers the fun of mathematics together through common and easy-to-understand language. Through observation and practice, we can understand mathematics from different angles. When children can retell the definition of the concept and explain the essential attributes revealed by the concept in popular language, it shows that children have a deep understanding of the concept.
