See Figure 1 below. The model is also referred to as a concrete-semi concrete-abstract (CSA) model [21].The model is the number line. The strategy is making jumps of 10. Teaching how to use number lines when using 10 to add +9 and +8 facts, solidifies this strategy when students are adding larger two-digit numbers. Remember, the number line is the model and can be used with various strategies.

The model method is synonymous with Singapore Mathematics. The spiral structure of the mathematics curriculum, with its focus on problem solving, and the concrete-pictorial-abstract approach to teaching, supports the use of the model method to solve arithmetic problems and enables the development of letter-symbolic algebra.

The Concrete, Pictorial, Abstract approach (CPA) is a highly effective approach to teaching that develops a deep and sustainable understanding of maths in pupils. Often referred to as the concrete, representational, abstract framework, CPA was developed by American psychologist Jerome Bruner.

In teaching practices enriched with concrete models, students’ tendency to see mathematics as a discipline isolated from real life is eliminated, and they are made to realize that a way of thinking that produces solutions to real-life problems through models is a dimension of mathematics (Milli Eğitim Bakanlığı [MEB], 2018).Stephanie Stanglin is a license secondary mathematics teacher with 4.5 years experience as math teacher, .66 years as a K-12 mathematics coach, and .33 years as a 3-10 mathematics tutor.The use of so-called ‘concrete’, ‘illustrative’ or ‘real-world’ examples has been repeatedly proposed as an evidence-based way of enhancing the learning of abstract concepts (e.g. Deans for Impact, 2015; Nebel, 2020; Weinstein et al., 2018).Abstract concepts are defined by not having a physical form and so can be difficult for learners to process and understand …1.3 Number and operations.

Oct 23, 2019 · The CRA (Concrete-Representational-Abstract) Model is an instructional model where we move through stages of teaching/learning. In this post we will consider this model in terms of basic multiplication facts. In the concrete stage, we work with manipulatives and objects in order to develop an understanding of what multiplication really means. Students use concrete materials to solve problems that involve comparing, combining and separating sets. Students make ‘groups’, ‘lots’ and groups of ‘one’ and can indicate which collection has ‘more’ than the other. ...

They have to learn that the value of a digit depends on its place in a number. For example, students should understand that in the number 142, the digit 1 has a value of 1 hundred. The digit 4 has a value of 4 tens, and the digit 2 has a value of 2 ones.

An example of Mathematical modeling is using concrete models, which are tangible objects that aid in the connection between Mathematics concepts and abstract symbols.Introduce concepts and skills using concrete manipulatives, like using base 10 blocks to teach place value. Show concepts and skills using representations and pictures, like tallies, dots, and circles. Model concepts and skills at the abstract level, like using numbers and symbols. Provide students with practice opportunities at each stage. How to teach using the Concrete Pictorial Abstract method at primary school. A common misconception with this CPA model is that you teach the concrete, then the pictorial and finally the abstract. But all stages should be taught simultaneously whenever a new concept is introduced and when the teacher wants to build further on the concept.Discrete mathematics is the study of mathematical structures that can be considered "discrete" (in a way analogous to discrete variables, having a bijection with the set of natural numbers) rather than "continuous" (analogously to continuous functions).Objects studied in discrete mathematics include integers, graphs, and statements in logic.
