A model is a simplified substitute for the real problem, allowing us to solve the problem in a relatively simple way.
Analysis models are previously solved problems that describe either (a) the behavior of some physical entity or (b) the interaction between that entity and the environment.
Geometric models form geometric constructions of real situations. We then analyze the geometric construction. These are commonly used in trigonometry.
Simplification models ignore insignificant details.
Structural models make it easier to understand concepts which are relatively abstract. For example, thinking of an election as a cloud of electron density is a structural model of an electron.
Thinking of problems from different perspectives will oftentimes help you figure things out.
Mental representations occur when you imagine a scene based on a description in a word problem. You envision a sequence of events and can predict what will occur in the future.
Pictorial representations occur when you draw your mental representaition. The drawing describes what you would see if you were observing the situation in the problem.
Simplified pictorial representations are pictorial representations to which a simplification model has been applied.
Graphic representations are graphs which represent situations in problems
