Pupils very often face need to define a case of nouns. It needs to be done, for example, when it is necessary to check writing of an unaccented vowel in the termination. The difficulty arises during distinction of imenitelny and accusative cases since auxiliary questions to the words used in these cases are almost identical.

1. To define a case of nouns, it is necessary to raise, first of all, a question to a word. The words relating to the Nominative case answer questions WHO? WHAT? If you raised questions WHOM? or WHAT?, before you the noun used in the form of an accusative case.
2. Define what sentence part is the noun. If the word is a subject, i.e. the principal part of the sentence, then it is used in the form of the Nominative case. The accusative case designates a word which is in the offer a minor member, a direct object. For example, suggest children to define a case of nouns in this offer. The girl writes the letter. Ask them to raise questions to words, to define what sentence part they are. They have to come to the following result. The word ""girl"" answers question WHO?, is a subject, means it is used in the Nominative case. And the word ""letter"" is secondary part of the sentence, a direct object. It answers question THAT? and, therefore, it is used in an accusative case.

So, in nouns of the first inducement there will be terminations A, Ya if they stand in the form of the Nominative case. Respectively, in an accusative case - At, Yu. Naprimer, in at a noun of the first inducement ""wall"" termination A. It is used in the Nominative case. The word ""wall"" has termination U. Means, it has an accusative case.
