拓展乘法表规律

识别并运用重复推理进行概括：拓展乘法表规律，从已知事实推导出未知事实，并描述数列的规则。

Recognise and use repeated reasoning to generalise: extend multiplication table patterns, derive unknown facts from known ones, and describe rules for sequences

学习证据 / Evidence

• 注意到所有4的倍数都是偶数，并利用这一点来检查答案。
• 通过发现规律，从 8 × 5 + 8 × 2 推导出 8 × 7。
• 描述一个递增模式的规则（例如“每次加50”），并用它来预测接下来的几项。

• Notice that all multiples of 4 are even and use this to check answers
• Derive 8 × 7 from 8 × 5 + 8 × 2 by spotting the pattern
• Describe a rule for a growing pattern (e.g. 'add 50 each time') and use it to predict the next terms

评估问题 / Assessment

当{{name}}学习乘法表时，会利用已知算式来算出不太确定的算式吗——例如，用 5 × 6 = 30 推出 6 × 6 = 36？

When {{name}} is learning their times tables, do they use known facts to figure out ones they're not sure of — for example, using 5 × 6 = 30 to work out that 6 × 6 = 36?
