现实世界数学建模
Real-World Maths Modelling
选择合适的数学表达方式，对涉及比例缩放、单位换算、面积/周长和百分比的现实问题进行建模，并结合具体情境解释结果。
Model real-world problems involving scaling, unit conversion, area/perimeter, and percentage by selecting appropriate mathematical representations and interpreting results in context
学习证据 / Evidence
- 用乘法和分数为一个按比例调整食谱的问题建模，然后解释以克为单位的答案。
- 通过绘制比例图并运用面积公式，来表示一个房间铺地毯的问题。
- 使用百分比条形模型求出售价，并用英镑（£）解释答案。
- Model a recipe-scaling problem with multiplication and fractions, then interpret the answer in grams
- Represent a room-carpet problem by drawing a scale diagram and applying the area formula
- Use a percentage bar model to find a sale price and explain the answer in £
评估问题 / Assessment
当{{name}}在解决现实世界中的数学问题时，比如按比例调整食谱或换算单位，是否能够选择合理的表示方式、完成数学运算，并解释结果在实际情境中的含义？
When {{name}} is solving a real-world maths problem — like scaling a recipe or converting units — do they choose a sensible representation, carry out the maths, and then explain what the result means in the real situation?
