（7歲10個月，二年級上）Back to the sandpit
這是關(guān)于數(shù)數(shù)的一章，這幾乎是前幾本書是最容易理解的一章，幼兒園或一年級的小朋友如果要看這套書，竊以為可以從這里開始。
沙坑里原來有3個小朋友，又來了4個小朋友，有兩種數(shù)數(shù)的方法：
1）You could count them all and get to seven like this：1，2，3，4，5，6，7
2）You could start counting from three，and count up one number for each extra kid that joined in：4，5，6，7
You might not see much difference in these two methods，but it becomes more obvious with bigger numbers.
