精确的数学表达
Precise Maths Communication
用数学的精确性进行交流：使用正确的词汇、标明单位，并准确运用符号。
Communicate with mathematical precision: use correct vocabulary, specify units, and use symbols accurately
学习证据 / Evidence
- 能正确使用“=”表示“两边相等”的意思，而不是把它当作“答案是”来用。
- 在给出测量答案时注明单位（例如写“12厘米”而不是只写“12”）。
- 描述三维图形时使用准确术语，如“棱”“顶点”“面”；比较数字时使用“大于”“小于”。
- Use the = sign correctly to mean 'is the same as' rather than 'the answer is'
- Include units when giving a measurement answer (e.g. '12 cm' not just '12')
- Use precise terms such as 'edge', 'vertex', 'face' when describing 3-D shapes, and 'greater than', 'less than' when comparing numbers
评估问题 / Assessment
当{{name}}写或说数学答案时，会带上单位吗？比如写“5厘米”而不是只写“5”；会正确使用=或<这类符号吗？
When {{name}} writes or talks about a maths answer, do they include the units — like "5 centimetres" rather than just "5" — and use the right symbols like = or <?
