Hi,
I have much the same problem. I have Grade 3 and 4 ""Story" every week, but so far most of my classes have bombed.
I am going to try books that were used on me (Three little pigs, the little red hen etc etc...)
My main problem is, that when I feel that I have good material and have the lesson sorted, the Chinese teacher looks at it and says "It's too difficult", and when I dumb it down, the children get bored mindless...
If all goes well tomorrow I will send you what I have, it could help.
Regards
C
