Three Types of Sentences Explained

Khan Academy

A lively and humorous grammar tutorial that introduces students to the three main types of sentences: declarative, interrogative, and imperative. Through a conversational dialogue between two instructors, David and Paige, the video defines each sentence type, provides clear examples, and explains their specific grammatical functions. The visual format uses a blackboard style where terms and examples are handwritten in real-time to reinforce the concepts. The video covers the specific definitions of each type: declarative sentences for making statements or conveying facts/opinions, interrogative sentences for asking questions, and imperative sentences for issuing commands. A key grammatical concept explored is the "implied subject" in imperative sentences, where the subject "you" is understood but not spoken. The instructors use memorable, sometimes silly examples involving lavender, baseball, cheese, and bunnies to keep engagement high. This resource is highly valuable for elementary and middle school English Language Arts classrooms. It demystifies complex-sounding terminology (like "interrogative") by connecting it to familiar words (like "interrogation"). Teachers can use this video to introduce sentence variety in writing, teach proper end punctuation, or explain the grammatical structure of commands. The final segment, which transforms a single slogan into all three sentence types, offers a perfect model for classroom practice activities.
