Modern Russian language has six cases:
Nominative (answering the questions: who? what?) cat, chair;
Genitive (who? what?) cat, chair;
Dative (to whom? what?) cat, chair;
Accusative (who? what?) cat, chair;
By (by whom? what?) - a cat, a chair;
Prepositional phrases (who? what?) - the cat on the chair.

Quickly memorize the order of these affixes will help a little poem:
Ivan Gave Birth To A Girl
Told To Drag The Diaper.

Or:
Ivan Begat Darenko,
Told To Drag The Diaper.

The initial letters of the words of these poems coincide with the initial letters of the names of the cases:
And - nominative, genitive, D - dative, a - accusative, T - by, P - prepositional.
These verses you can use to help myself and dedicated to the cases the lessons of the Russian language BB school.

If the order of cases to remember is very simple, the questions require a little more attention and time. When memorizing case of questions will help "support words". Some of them are combined with the names of the cases in meaning, and therefore facilitate the memorization process.
Nominative case: there is no auxiliary words, so as this case it is easy to remember. For example: the river, son.
Genitive: the word "no". No who? No what? (no), (no) son.
Dative: the word "give" or "donate". To give someone? To give what? (to) the river, (to give) son.
Accusative case: the word "blame". Blame who? Blame what? (blame) (blame) son.
The instrumental case: the word "proud". Suit whom? Be proud of it? (proud) (proud) son.
Prepositional case: the word "speak". To speak about whom? Talk about what? (speak) on the river (talking) about his son.
The use of these auxiliary words will help to quickly and correctly memorize questions cases.
