按属性对形状分类
Classifying shapes by properties
比较并依据属性与大小对几何形状进行分类；理解属于某个类别的属性也属于该类别下的所有子类别；依据属性将二维图形放入层级结构中分类。
Compare and classify geometric shapes based on their properties and sizes; understand that attributes belonging to a category also belong to all subcategories; classify two-dimensional figures in a hierarchy based on properties
学习证据 / Evidence
- 解释为什么所有的正方形都是长方形，但并不是所有的长方形都是正方形
- 将四边形放入层级图中，以显示子集关系
- 找出所有平行四边形共有的属性，并解释为什么菱形和长方形是特殊情况
- Explain why all squares are rectangles but not all rectangles are squares
- Place quadrilaterals in a hierarchy diagram showing subset relationships
- Identify properties shared by all parallelograms and explain why rhombuses and rectangles are special cases
评估问题 / Assessment
如果有人问{{name}}“正方形也是长方形吗？”，他们能解释为什么答案是肯定的吗——因为正方形具有长方形的所有属性，并且四条边都相等？
If someone asks {{name}} "is a square also a rectangle?", can they explain why the answer is yes — because a square has all the properties of a rectangle plus equal sides?
