有个问题一直忘记请教各位,
小刘每个礼拜有这样一项作业,
叫做extended response,
其实就是一道简单的数学题,
类似树上有4只鸟,又飞来6只鸟,请问现在一共几只鸟?
.......
我儿子说:
first: 4 6
then:4+6
Last:4+6=10
不知道是不是要加语言描述的,是不是这样:
first: There were 4 birds in a tree. Then came 6 birds .
then: How many birds are there in the tree now?
Last: There are 10 birds in the tree.
