This activity is great for building vocabulary and working on grammar.

Sentences are a series of words that complete a thought and they all contain a subject and a predicate. The subject is who or what of the sentence. You can locate subjects by looking for the action word (verb), the who or the what that is performing that action is the subject. The section of the sentence that modifies the subject is called the predicate. The predicate always includes the verb. Sentences can present as basic statements, commands, exclamations, or questions. Complete sentences have several characteristics. They begin with a capital letter and end with a mark of punctuation. The punctuation mark indicates the nature of the statement that is being made. A question mark tells it is a question. A period indicates a statement or command. An exclamation point tells us it can either be a cry out or command.

In some cases that will be just a word and sometimes a phrase. At the 2nd grade level, we are working toward understanding a little more grammar mechanics. We expect students to be able to not only understand the definition of the words that they are placing, but also where to use those words in context. Students will be tasked with writing a complete thought after being given a starting or ending prompt. We then have students write their own sentences when given a word to put into context. While this may seem like a pointless exercise this can really help extend your ability to express yourself with language. This series of worksheets will be missing something. You are tasked with determining what is missing to make it a complete sentence.
