乘法比较

将乘法算式解释为一种比较关系（例如，35 = 5 × 7 表示 35 是 7 的 5 倍）；并能用等式表示乘法比较的语句。

Interpret a multiplication equation as a comparison (e.g. 35 = 5 × 7 means 35 is 5 times as many as 7); represent verbal statements of multiplicative comparisons as equations

学习证据 / Evidence

• 能解释“是……的4倍”就是用这个数乘4。
• 能写出等式：莎拉的贴纸数是汤姆的3倍，汤姆有8张贴纸。
• 能在应用题中区分乘法比较关系和加法比较关系。

• Explain that '4 times as many' means multiply by 4
• Write an equation for: Sarah has 3 times as many stickers as Tom, who has 8 stickers
• Distinguish multiplicative comparison from additive comparison in word problems

评估问题 / Assessment

{{name}}能看着“35 = 5 × 7”并把它解释为“35 是 7 的 5 倍”吗？也就是理解它是一种比较关系，而不只是一条乘法算式？

Can {{name}} look at '35 = 5 × 7' and explain it as '35 is five times as many as 7' — understanding it as a comparison, not just a multiplication fact?
