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. One such relationship, the inverse relationship between division and multiplication, can be effectively illustrated using arrays. For example; 3×5=15 or 3 rows of 5 make 15, can be represented by the following array. Looking at the array differently reveals the inverse, that is. 15÷3=5 or 15 put into 3 rows makes 5 columns - or 5 in each row.A model is called concrete if the meanings assigned are objects and relations from the real world, as opposed to an abstract model which is based on other axiomatic systems.
