在现实情境、图画和算式之间灵活转换，并解释每种表征与其他表征之间的联系（数量推理）。
Move between real-world situations, drawings, and number sentences, explaining how each representation connects to the others (quantitative reasoning)
学习证据 / Evidence
- 写出与应用题匹配的算式（如 14 + 5 = 19），并解释其中的联系
- 画出条形模型或部分-整体图来表征问题，并利用图示解决问题
- 在具体模型与符号等式之间进行转换，并描述每个数字代表什么
- Write a number sentence (e.g. 14 + 5 = 19) to match a word problem and explain the connection
- Draw a bar model or part-whole diagram to represent a problem, then solve using the diagram
- Translate between a concrete model and a symbolic equation, describing what each number represents
评估问题 / Assessment
