Learn how a sentence is put together with character-based instruction, engaging practice worksheets, dynamic writing prompts and exercises, and quizzes to check comprehension. Based on the revolutionary Grammaropolis approach, this skill-building workbook makes learning grammar fun!

The Sentence Factory is hiring! Now that you know the parts of speech and punctuation, we need you to help us build our town's #1 export: grammatically correct sentences. Let the Mayor take you on a tour of the factory, where you'll learn about subjects and predicates, phrases and clauses, types of sentences, direct and indirect objects, subject and object complements, and more!

The ultimate goal of learning grammar isn't to do well on worksheets and quizzes, though, which is why we've included sentence and paragraph writing exercises to put every grammatical concept into practice.
