精准数学词汇

用数学语言进行精确表达：能正确使用质数、因数、倍数、角的类型和正多边形相关的词汇；能标明单位，如 cm²、m³、°；能准确使用平方、立方和百分数的符号。

Communicate with mathematical precision: use correct vocabulary for primes, factors, multiples, angle types, and polygon regularity; specify units including cm², m³, °; use notation for squares/cubes and percentages accurately

学习证据 / Evidence

• 在书面解释中能区分“factor”和“multiple”
• 把面积答案写成 48 cm²（而不是只写 48），把体积估算写成约 60 cm³
• 能正确使用 5² 的记法，并将其读作“five squared”

• Distinguish 'factor' from 'multiple' in a written explanation
• Write an area answer as 48 cm² (not just 48) and a volume estimate as approximately 60 cm³
• Use 5² notation correctly and read it as 'five squared'

评估问题 / Assessment

当 {{name}} 在谈论或书写涉及质数、百分数或多边形的数学内容时，能否正确而自信地使用精确的术语——例如“prime factor”、“obtuse angle”或“regular hexagon”？

When {{name}} talks or writes about maths involving primes, percentages, or polygons, do they use the precise technical words — like "prime factor", "obtuse angle", or "regular hexagon" — correctly and confidently?
