Why Mastering Maths Models Matters for Students
A mathematical model describes a system by using mathematical concepts and language. The process through which a mathematical model is developed is called mathematical modelling.
The importance of mathematical models is vast as it has considerable stretch in natural science, which includes physics, biology, chemistry, earth science as well as in engineering disciplines consisting of computer science, electrical engineering. Furthermore, mathematical modelling has a strong presence in non-physical systems which includes subjects like economics, sociology, political science etc. Mathematical models assist in elaborate systems, to learn the effects of different components and to provide predictions about behaviour. In short, mathematics can be applied as a medium to model or represent the real world.
In this section, students will learn about the maths model based on mathematical concepts from class 5-10. Students who are willing to get a clear mathematical concept regarding their respective syllabus can easily refer to this discussion while preparing a maths model.
Maths Models for Class 10
Studies are no longer restricted to only reading, writing and revising. To create various math models, students of class 10 can easily depend on their respective syllabus and several mathematical formulas. Below is a discussion of some ideas using which 10th standard students can make various math models.

3. Representation of Circles, Tangents, Radius, Secant, Chords, Sector-
Draw out different types of circles and its tangents radius, secant, chords, sector in a paper chart.
Maths Model for Class 9
Students of class 9th standard can make use of the following models based on their syllabus.
1. Area of Rhombus
At first draw out a rectangle and outline it with a colour pencil. Then, draw a rhombus inside the rectangle and fill it with a different colour. Connect the corners of the rhombus with a dotted line. This model helps to prove that the area of the rhombus is half of the area of a rectangle.
2. Angle Sum Property of Quadrilaterals
In a paper chart, draw out a quadrilateral and its angles with different colours. Then create a circle by joining those angles to show the fact that the sum of the interior angles of a quadrilateral is 360 degrees.
Math Model for Class 8
The following ideas regarding their syllabus will help students to make various maths models.
1. Algebraic Formulas
To make the algebraic formulas more interesting, students can use various blocks of colourful papers for each term in a formula and paste it on a paper chart following the formulas.
2. Polygons
To make a maths model on polygons, cut various colourful papers and paste it in increasing order on a white chart.
Math Model for Class 7
Students of class 7 can easily create math models with the given ideas.
1. Types of Angles
Draw different types of angles, including acute angle, obtuse angle, right angle with the use of coloured pencils.
2. Lines and Transversal
To show lines and traversal, first take a piece of Styrofoam and cut two parallel lines and traverse it using a cutter. Then point out the eight angles that have been generated by a traversal on the crossing path of two lines.
Math Models for Class 6
By using the given simple models, students can utilize the process in creating them.
1. Prime and Composite Number of Charts
To memorise the prime and composite numbers more efficiently, outline a table in a paper chart. Put the numbers from 1-100 in each block. Then colour only the prime numbers.
2. Clocks
Take a cardboard and needle to create a wall clock and show different timings with the needle.
Maths Model for Class 5
Below are some examples of maths models which help students to easily understand the concept behind it.
1. Shapes and Angles
Take a big paper and draw different shapes such as triangle, rectangle, square with colourful pencils. Likewise, draw different angles.
2. How Many Squares
In a white paper, first draw a big rectangle with a colour pencil. Then, inside the rectangle, draw as many squares as possible with different colour pencils to show how many squares can be drawn in a rectangle.

FAQs on Maths Model: Concepts, Types & Applications
1. What is a mathematical model in simple terms?
A mathematical model is a way of representing a real-world system or problem using mathematical language, such as equations, functions, and geometric figures. Its main purpose is to help us understand how a system works, analyse its behaviour, and make predictions about the future. For example, an equation that predicts population growth based on birth and death rates is a mathematical model.
2. What are the main types of mathematical models used in school-level maths?
While there are many complex types, mathematical models at the school level can generally be understood through a few basic categories. These types help in visualising and solving problems:
- Algebraic Models: Using equations and variables to represent relationships, such as modelling profit with a linear equation.
- Geometric Models: Using shapes, diagrams, and graphs to represent problems, like using coordinate geometry to map a location or applying theorems to design a structure.
- Statistical Models: Using probability and data analysis to understand trends and make predictions, like modelling the outcome of a coin toss or analysing survey data.
3. What are some real-world applications of mathematical modelling?
Mathematical modelling is essential in almost every field. Some key applications include:
- Weather Forecasting: Using complex equations to predict temperature, rainfall, and storm paths.
- Finance: Modelling stock market trends and investment risks.
- Engineering: Designing bridges, aircraft, and circuits by modelling physical forces and electrical flows.
- Epidemiology: Predicting the spread of diseases within a population to plan for healthcare needs.
- Traffic Control: Creating models to optimise the timing of traffic lights and reduce congestion.
4. How is a mathematical model different from a simple formula like the area of a circle?
This is a key distinction. A formula like A = πr² is a component, but a mathematical model is the entire framework. A model includes:
- The Formula(s): The core mathematical relationship.
- Assumptions: The conditions under which the formula is valid (e.g., assuming the shape is a perfect circle).
- Variables: Clearly defined inputs (radius) and outputs (area).
- Interpretation: How the result relates back to the real-world problem.
In essence, the formula is just the calculation, while the model is the complete logical structure for solving a problem.
5. What are the basic steps to create a mathematical model for a problem?
Creating a mathematical model generally follows a structured process:
- Identify the Problem: Clearly define what real-world question you want to answer.
- Make Assumptions: Simplify the problem by identifying and ignoring less important factors. For instance, when modelling a falling object, you might initially ignore air resistance.
- Formulate the Model: Translate the problem into mathematical language by choosing variables and writing equations that connect them.
- Solve the Model: Use mathematical techniques to solve the equations and find a result.
- Validate and Refine: Compare your model's prediction with real-world data. If it's not accurate enough, revisit your assumptions and refine the model.
6. Why are mathematical models important for a student's learning?
The importance of creating and using maths models goes beyond just finding an answer. They are crucial for developing critical thinking skills. By building a model, students learn to connect abstract mathematical concepts to practical, real-life situations. This process enhances problem-solving abilities, deepens the understanding of theoretical knowledge, and boosts confidence in applying maths to unfamiliar challenges.
7. Can a mathematical model ever be perfectly accurate? What are its limitations?
No, a mathematical model can never be 100% accurate because it is a simplification of reality, not reality itself. Its primary limitation comes from the assumptions made during its creation. For example, a weather model might not account for a sudden, unpredictable event. Other limitations include the availability of precise data and the inherent randomness in many natural systems. The goal of a good model is not to be perfect, but to be useful and accurate enough for its intended purpose.
