Ian, one of my students, was particularly frustrated by visual models. Several students told me on the first day of school that Ian was the “best math student in the grade.” And they were right in their estimates.
Sure, they’d done some philosophical work in elementary school. Ian, on the other hand, had learned to keep his distance during these events. It was all about calculation when it came to exams and quizzes. This is his strong suit.
It was not necessary to opt out of visual templates in my class. Assessments and training go hand in hand for me. As a result, I changed my tests and quizzes once we began using visual representations. Students were required to interpret and create their own models. Community tasks, such as designing displays and animated visual templates, were also part of their grades.
While several of his classmates excelled, Ian sulked. The game’s rules had changed. The only criterion for performance was no longer “math facts.” Other students started to recognize the worth of their own abilities. The importance of problem solving and visual representations was equal to that of arithmetic. Students who had previously dismissed themselves as “math people” started to participate actively in class.

A mathematical model is a language and mathematical concepts-based explanation of a system. Mathematic modeling is the method of constructing a mathematical model. Mathematical models are used in natural sciences (physics, biology, earth science, chemistry), engineering disciplines (computer science, electrical engineering), and non-physical structures (such as the social sciences) (such as economics, psychology, sociology, political science). Music, linguistics, and mathematics all use mathematical models.
Dynamical structures, statistical models, differential equations, and game theoretic models are all examples of mathematical models. These and other types of models will mix and match, with a single model encompassing a wide range of abstract structures. In general, logical structures can be used in mathematical models. In certain cases, the consistency of a scientific area is determined by how well theoretical mathematical models agree with the results of repeatable experiments. As better theories are established, a lack of agreement between theoretical mathematical models and experimental measurements often leads to significant advancements.

Providing students with opportunities to work with all three models is critical for gaining a conceptual understanding of fractions. It may also be helpful to have students replicate an exercise with a different model and ask them to make associations between them. Students also study rules for manipulating written fractions before developing a grasp of fraction concepts. Fraction models may assist students in clarifying concepts that are often misunderstood in a strictly symbolic mode and constructing mental referents that enable them to perform fraction tasks meaningfully.
1. MODEL OF THE AREA: Fractions are defined as parts of an area or region in the area model. Rectangular or circular fraction sets, pattern blocks, geoboards, and tangrams are all useful manipulatives. Fraction sets, whether rectangular or circular, can be used to help students understand that fractions are pieces of a whole, compare fractions, produce equivalent fractions, and explore fraction operations. The circular model emphasizes the part-whole idea of fractions and the sense of the relative size of a part to the whole, whereas the rectangular model is simpler for students to draw precisely (Cramer, Wyberg & Leavitt, 2008). As a result, students should have access to both rectangular and circular versions. When buying rectangular or circular fraction sets, bear in mind that those with unlabeled pieces provide more learning opportunities. Labeled kits deprive students of opportunities to understand the size of the pieces in relation to the whole, as well as leading them to believe that only one of the pieces can be considered the whole, making them less useful when focusing on definition of unit activities in which students call fractions when the unit is varied.
