What is Descriptive Math Modelling? Using math for solving real world problems is important to learn as far as academics are considered. Once you have created a model, you will be able to use the mathematical equations that will help you solve your problems. The process of creating models such as these is called descriptive modelling. Descriptive modelling requires gathering information in the initial phases. Once you have catered to the difficult part where you find the answers, you create a model of a situation. You ask yourself what kind of calculations are involved here. You need to decide on the physics that show the force and its impact when two or more objects collide with each other. In the next stage, you label the variables based on your created model. Suppose you have two cars, and they both have a speed of travel and a force of impact. Then you will use your variables and other information to solve your problems. Once the variables have been labelled and other information, you can model then follow the model that helps you determine the speed at which object is traveling. These worksheets and lessons will help students better understand how use descriptive modeling to understand and solve real world problems.
