In the classroom vignette that follows, Mr. Dominguez, a first-grade teacher, is working with students using rekenreks along with part-whole bar models to build fluency of basic addition facts based on number sense (Virginia Mathematics Standards of Learning (SOL) 1.7) and to explore the concept of equality (SOL 1.15).Platonism about mathematics (or mathematical platonism) is the metaphysical view that there are abstract mathematical objects whose existence is independent of us and our language, thought, and practices.Just as electrons and planets exist independently of us, so do numbers and sets. And just as statements about electrons and planets are made true or false …What are concrete models in math? In the concrete stage, the teacher begins instruction by modeling each mathematical concept with concrete materials (e.g. red and yellow chips, cubes, base ten blocks, pattern blocks, fraction bars, geometric figures). Representational. The “seeing” stage uses representations of the objects to model problems.In addition, students should use models and concrete objects to justify their thinking. In third grade, students use various strategies to solve word problems. Expect students to use a variety of representations when solving problems, such as rectangular arrays, drawing pictures of equal groups, mental math, number lines, and equations.between mathematical concepts and concrete models. Kamina-Iyer [43] also stated that pre-service teachers had difficulty in transferring knowledge from enactive concrete models to mathematics symbols and abstraction.For that reasons it is important for pre -service teacher s to gain skills of using concrete models.B) Counts out sixteen and puts the 10 in one pile and 6 in another and tells you there are sixteen. C) Counts out sixteen and makes two piles of eight and tells you there are sixteen. D) Counts out sixteen and places 6 aside and tells you 10 and 6 are sixteen. Answer: A) Counts out sixteen objects and can tell you how many by counting each piece.Concrete representation is when a math concept is introduced with manipulatives. So, when students are working with manipulatives, this is the representation we are focusing on. Examples. We are helping students make meaning of abstract concepts by giving them a visual of that concept to manipulate. Some examples include:5th Grade Common Core: 5.NBT.7.

We see the relation between 1/3 and 2/6 in the paper cuttings, or in the ready-made fraction material. For the students, who do not bring our mathematical knowledge to the table, these are just blocks of various sizes. While trying to take an actor's point of view, we have to lookstanding 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.The Importance of Concrete Reasoning. Concrete reasoning is important because it is the basis of all knowledge. Students need a firm understanding of basic educational concepts and problem-solving. This enables them to learn new ideas. It helps with later learning because it gives students the ability to link new ideas to previously learned ideas.Concrete Math ; Learning through Physical Manipulation of Concrete Objects. Build it!
