Concrete, Representational/Visual/Pictorial, and Abstract/Symbolic Models. Using multiple representations to teach mathematics allows students to understand mathematics conceptually, often as a result of developing or "seeing" an algorithm or strategy on their own.

a thorough understanding of math concepts, CRA instruction allows students to make associations from one stage of the process to the next. When students are allowed to first develop a concrete understanding of the math concept/skill, they are much more likely to per-form that math skill and truly understand math concepts at the abstract level.

Note. Python programmers will probably prefer to write concrete models, while users of some other algebraic modeling languages may tend to prefer to write abstract models.Some know this idea as concreteness fading, while others have called this progression concrete, representational, abstract (CRA). In either case, the big idea is the same. Start with concrete manipulatives, progress to drawing those representations and finally, represent the mathematical thinking abstractly through symbolic notation. Kaminski et al. (2009) had 11-year olds learn a mathematical concept either concretely with perceptually rich symbols or abstractly with symbolic models. Although the concrete model made learning easier, it resulted in less transfer, whereas the symbolic model made learning harder but resulted in greater transfer.Using concrete models to work out math stories allows students to see the problem and manipulate the pieces as the story progresses.
