Sentence Builder Pro: Simple, Compound, and Complex Sentences (Intro) – Class 4 

This Grade 4 worksheet on Simple, Compound, and Complex Sentences introduces students to how sentences are structured using clauses and conjunctions. Through classification tasks, multiple-choice identification, sentence rewriting, passage analysis, and guided paragraph writing, learners understand how ideas connect to form meaningful and grammatically correct sentences. Students begin by identifying sentence types, then choose correct examples of each type. They practise converting sentences between types, analyse compound and complex sentences in a passage, and finally apply their understanding by writing a paragraph that includes all three sentence forms. This structured progression strengthens grammar clarity, writing fluency, and logical expression.
