Dec 3, 2021 · Stage 1: Concrete and action-based representation using manipulatives like money, counters, cubes, base ten blocks and dice to explore and solve problems — think of it as the ‘doing’ stage. Stage 2: Pictorial representations of concrete objects such as bar models are used to model problems — the ‘seeing’ stage. A pear, a grape, a juicy pineapple—these are all concrete words because we can hold a pear in our hand, taste a grape, and smell a ripe pineapple; they’re tangible. In contrast, success, failure, and a mathematical equation are abstract concepts because we can’t touch failure, we can’t taste an equation, and we can’t smell success.Hughes (1986) asked 5- to 7-year-olds to solve simple problems, such as 1 + 7 = 8, with toy bricks. The children were told to use the bricks to show the written problems. Thus, children were asked to translate the abstract, symbolic representation of the written problem into a concrete representation with the bricks.Concrete, Representational/Visual/Pictorial, and Abstract/Symbolic Models.
