Bar models are a visual teaching tool that can effectively aid in understanding addition by representing numbers and their relationships in a concrete manner. They use rectangular bars to symbolize different quantities, making it easier for students to see how they combine to form a sum. This visual representation helps bridge the gap between abstract numerical concepts and tangible understanding.
