Option 2 : Setting up equations for a word problem.
Mathematical modeling is the process of describing a real-world problem in mathematical terms, usually in the form of equations, and then using these equations both to help understand the original problem and also to discover new features about the problem. Features of mathematical modeling:
- Mathematical modeling is capable of saving lives, assisting in policy and decision-making, and optimizing economic growth.
- Mathematical modeling is described as the conversion activity of a real problem in a mathematical form.
- Modeling involves formulating real-life situations or to convert the problems into mathematical explanations into a real or believable situation.
- In the above examples of setting up equations for a word, a problem is an example of mathematical modeling because here the student first reads and understands the problem and then derives the values in the form of words to equations.
Hence option 2 is the correct one.
On the other hand efficient use of calculating devices, using mathematical tricks, and making models of 3D shapes are not examples of mathematical modeling as the students are not involved in formulating the real-life situations to mathematical equations.
