The Model Method
Also known as “Singapore model method,” “bar model method,” or “bar modeling.” A problem-solving visualization strategy whereby the problem solver makes use of rectangles or bars to draw a model diagram to represent how the known and unknown quantities in a given problem situation are related, using a part-whole or comparison model.
Using the model method to solve a word problem involving fraction, ratio, or percentage allows the mind’s eye to better grasp the problem situation by making tacit knowledge more explicit or visible—it’s like a “look-see” proof to a problem for kids.
