发现高效方法
Finding efficient methods
注意计算或规律中的重复之处,并利用这些重复来更高效地数数或预测结果。
Notice when a calculation or pattern repeats and use this to count more efficiently or predict results
学习证据 / Evidence
- 注意到按2个一数会呈现奇偶交替的重复规律。
- 认识到给任何一个数加1,总是得到数数时的下一个数。
- 利用重复规律来预测答案(例如,在百数表上+10总是向下移动一行)。
- Notice that skip counting by 2s follows a repeating odd/even pattern
- Recognise that adding 1 to any number always gives the next counting number
- Use a repeated pattern (e.g. +10 on a hundred chart always moves down one row) to predict answers
评估问题 / Assessment
当{{name}}在数数或做重复加法时,是否已经能注意到规律——比如“5、10、15、20……”——并利用它来预测下一个数,而不是一个一个地数?
When {{name}} is counting or doing repeated additions, have they started to notice the pattern — like "5, 10, 15, 20…" — and used it to predict the next number without counting one by one?
