A good teacher+good learning materials with good exercises + lots of repetition and practice.

Russian schoolchildren learn by rote the words given in brackets: Именительный - (это) Кто/Что Родительный - (нет) Кого/Чего Дательный - (даю)Кому/Чему Винительный - (вижу)Кого/Что Творительный - (владею) Кем/Чем Предложный - (говорю) О ком/О чем I am not sure if it would be helpful for a foreign-language speaker, but it was most helpful when I was at school. It is a big problem for a Russian kid to learn all these cases.

I will look into it! Thank you very much))) ;)

I think this guy gives a very god explanation about the russian cases. Also it is very good because he is not russian-speaker, so he might explain everything in a more understandable way. https://www.youtube.com/watch?v=J1SrQ6lzGks
