An article (abbreviated art) is a word that combines with a noun to indicate the type of reference being made by the noun. Articles specify the grammatical definiteness of the noun, in some languages extending to volume or numerical scope. The articles in the English language are 'the' and 'a/an'. 'An' and 'a' are modern forms of the Old English 'an', which in Anglian dialects was the number 'one' (compare 'on', in Saxon dialects) and survived into Modern Scots as the number 'ane'. Both 'on' (respelled 'one' by the Normans) and 'an' survived into Modern English, with 'one' used as the number and 'an' ('a', before nouns that begin with a consonant sound) as an indefinite article. The word some is thus used as a functional plural of a/an. "An apple" never means more than one apple. "Give me some apples" indicates more than one is desired but without specifying a quantity.
English language learners often forget when and where to include articles in their sentences but these words are important to master in order to achieve a high level of English. There are 240 worksheets that you can give your students for extra practice using articles and these are sorted into several different categories to make your search simpler. Here is a worksheet that practices not only articles but also countable and uncountable nouns. You will need to introduce and practice the material before completing the three activities outlined in this file. Students will enjoy the variety of games and the worksheet will enable you to evaluate their overall understanding of the material at the end of class or as a review activity at the beginning of the next lesson. There are more worksheets to choose from if this is not quite what you are looking for so take your time reviewing them.
Articles are often overlooked or misplaced by English language learners so it is important to give them sufficient practice with word order. Another way you can help students learn articles is to introduce nouns with a or an; instead of drilling book, consider using a book instead. This will help students when it comes to forming sentences because they will say I want a book. rather than the common, incorrect answer I want book. Other articles will obviously need to be introduced in a different way but getting students accustomed to using articles in sentences will make it easier for them later on in the course.
