Disclaimer: I am not a teacher and English is not my first language.

I am currently helping to teach English at a small village school in Thailand. I will be there for another two weeks. I teach Prathom 3, 4, 5 and 6 students with an age range from 9 - 12 years. The total number of students I teach is 19. Their general knowledge of English is very bad, with the Prathom 6 students being the worst. I tried to find out from their Thai teachers what subjects have to be covered up to the end of Prathom 6. Unfortunately they have no idea whatsoever.

I now try to find out what kind of English knowledge children should have after having been taught English for four years with three hourly lessons per week; I estimate they will have about 120 hours of English lessons annually. What tenses should they know, what vocabulary knowledge should they have, what other subjects should be covered, etc. I know I won't be able to do much in two weeks, but at least I want to teach them as much usefull stuff as possible.

If there is anybody here who could point me in the right direction, I would be very grateful.
