Sentence structure skills for 3rd grade

Combining sentences Choose the sentence · answer key Two short sentences about the same thing can join into one smoother sentence. Use a joining word, and say repeated words only once.
Complex sentences Choose the word · answer key A complex sentence has a part that cannot stand alone, hooked to a part that can. Words like because, when, and although start the hanging part.
Expanding sentences Fix it · answer key A short sentence can grow. Add the words in parentheses where they fit best, and keep the capital and the period.
Run-on sentences Fix it & Choose the sentence · answer key A run-on squeezes two sentences into one. Find where the first idea ends, then add a period and a capital letter.
Sentence fragments Choose the word · answer key A fragment is a piece of a sentence. Find what it is missing: the naming part (subject) or the telling part (predicate).
Simple and compound sentences Choose the word · answer key A simple sentence has one who-did-what. A compound sentence is two of them, joined by a comma and a word like and, but, or so.
Subject and predicate Identify · answer key The subject names who or what the sentence is about. The predicate is everything the sentence says about it, starting with the verb.
Types of sentences Choose the word · answer key A statement tells. A question asks. A command orders. An exclamation bursts with feeling.
