I think you should learn some basic patterns (about 5-10) and figure some problems out, like "to have" problem and so on. Afterwards you might try to communicate in Russian. I can understand you, because I can see your English thinking through the Russian sentences. Also I'm a bit experienced in teaching beginners. But other people may be not so shrewd.
