And then the R stands for Representation. This is typically where we have kids draw a model or a representation of the concrete things we’ve been doing. And then the Abstract is when we attach symbols, so it’s the abstract world of mathematics.First, the Montessori practical life and sensorial activities give indirect preparations for math. Then the math materials continue to prepare the child for later learning. They use concrete materials to introduce abstract concepts and give a sequential understanding of mathematical concepts.Concrete math is a foundational practice that lays the groundwork for later abstract problem solving. Used extensively in preschool and early grades, it starts with what young learners already understand and builds upon it. It gives teachers and parents a way to introduce abstract ideas, such as adding or dividing, in a tangible way.Algebra permeates all of our mathematical intuitions. In fact the rst mathematical concepts we ever encounter are the foundation of the subject. Let me summarize the rst six to seven years of your mathematical educa-tion: The concept of Unity. The number 1. You probably always understood this, even as a little baby. #Concrete: 1/2 * 1/3 = 1/6 (This can be directly modeled by the teacher for a concrete math concept.) Abstract: 1/2 ÷ 1/3 = 1/2 * 3/1 = 3/2 (This is abstract because the student cannot perform ...The representation stage is when we start doing away with the manipulatives and we just have kids draw, just drawing a representation. And then the final stage is this abstract stage, where we’re just writing digits. This is also when we’re doing the algorithms, it’s seen as very abstract for kids.Here are three simple ways to move your learners from concrete to abstract thinking: 1. Move flexibly between CPA stages …As a teacher moves through a concrete-to-representational-to-abstract sequence of instruction, the abstract numbers and/or symbols should be used in conjunction with the concrete materials and representational drawings (promotes association of abstract symbols with concrete & representational understanding) [ back to top ]The fascination with mathematical outcasts has been a productive strategy too. Such objects often live at the intersection of multiple ideas and can act as an access point between completely different worlds. Aficionados of this style don’t care for “abstract nonsense” and cherish the peculiarities of the concrete case, warts and all.standing of mathematical concepts. Bastick (1993) has also argued strongly for the need to develop deeper understandings in this transition phase of learning. My experiences with ‘playdough maths’ provide evidence of effectively engaging learners in building bridges from concrete to abstract under-standing in mathematics.When working on math skills, it can be helpful to take more abstract concepts and demonstrate them with concrete objects and pictures.
