Teaching aids are tools used by teachers to help students learn, illustrate concepts, and engage students. They include flash cards, charts, diagrams, models, and audiovisual equipment. Effective teaching aids should be accurate, simple, meaningful, affordable, large enough for students to see, up-to-date, portable, and appropriate for students' level. They are classified as audio, visual, or audiovisual based on whether they use listening, viewing, or both. Projected aids like slides maximize learning through visual and auditory senses. Non-projected aids include charts and flashcards. Teaching aids provide clarity, engage students, motivate learning, save time and effort, and promote understanding.
