Sentence structure varies from language to language so learning how the parts of speech work together to form a grammatically correct sentence is the cornerstone of beginning ESL classes. Grammar worksheets for ESL students should provide practice in seven key parts of speech in the English language. Look for worksheets that help students learn the proper usage of nouns, verbs, adjectives, adverbs, prepositions, conjunctions and pronouns and give them practice in creating new sentences to become familiar with English word order.

Nouns
An ESL grammar worksheet should include practice naming people, places and things such as common items, community locations, vehicles, job titles, animals, proper names, and so on. The worksheet also needs to differentiate between common nouns, such a "house" and proper nouns, such as "The White House."

Pronouns
Once students firmly understanding nouns, they are ready for a worksheet on replacing some nouns with pronouns. Students should practice identifying the proper time to use subject (I, you, he, she, it, we, they), object (me, you, her, him, it, us, them), possessive (my, your, her, his, its, our, their) and demonstrative pronouns (this, that, those).

Verbs
Every English sentence must have at least a subject noun and a predicate verb. So identifying verbs needed to describe common activities, is an important part of worksheets for ESL students. Beginning students can start with simple present, past and future tense, such as "speak", "spoke" and "will speak" while intermediate and advance students can practice more advanced tenses such as "have spoken", "will have spoken", "was speaking", "should have been speaking", "would speak" and so on.

Modifiers
Nouns and verbs will only take a student so far with their communication needs so worksheets that provide practice in the various types of modifiers in the English language will help them express information that is more specific about their subject and predicate. Worksheets should provide practice with adjectives such as happy, sad, tall, short, colors and numbers as well as the articles, "a", "an" and "the." Practice with adverbs helps students learn to describe verbs with words such as, "slowly," "quickly," "beautifully" and "marvelously." A preposition worksheet introduces students to the structure of prepositional phrases that describe relationship or location. For example, "on the table," "under the chair," "behind the door" or "with me."

Conjunctions
Once they have mastered basic sentence structure, a worksheet on conjunctions, such as "and," "but," "or," "either...or" and "neither...nor" can help ESL students create more complex sentences to better express themselves in English.
