Fraction models are visual representations that help people understand fractions better. They can take various forms, such as number lines, pie charts, or bar models. Each model shows how a whole is divided into equal parts, making it easier to grasp concepts like addition, subtraction, and comparison of fractions. Using fraction models allows learners to visualize relationships between different fractions. For example, a pie chart can illustrate how much of a whole is represented by a specific fraction, while a number line can show the placement of fractions in relation to whole numbers. These tools enhance comprehension and problem-solving skills in mathematics.
