发现数学规律
Spotting mathematical patterns
注意简单的规律和结构：发现改变顺序不会改变总数，并认识数字之间的相互关系。
Notice simple patterns and structures: spot that changing order doesn't change the total, and recognise how numbers relate to each other
学习证据 / Evidence
- 发现3 + 2和2 + 3的答案一样（早期的交换律）
- 认识到十几的数就是“十和几个”，例如14就是10和4
- 在物体或数字的排列中发现规律，并预测接下来会是什么
- Notice that 3 + 2 gives the same answer as 2 + 3 (early commutativity)
- Recognise that teen numbers are 'ten and some more' (e.g. 14 is 10 and 4)
- Spot a pattern in a sequence of objects or numbers and predict what comes next
评估问题 / Assessment
{{name}}有没有注意到，把两个数加起来时顺序不同，答案也一样——比如3 + 5和5 + 3都等于8？他们能解释为什么这样讲得通吗？
Has {{name}} noticed that adding numbers in a different order gives the same answer — like 3 + 5 and 5 + 3 both equal 8 — and can they explain why that makes sense?
