Your idea about money is good, I often use it with my adults learners. As for the rest, I try and get my students to think about the reality underlying the representation. <br />For example 1/4 divided by a 1/2. <br />As is, no one knew. I then moved back and said division is asking how much of one number is in another. So how many halves in two?<br />Say two Pizza's how many half Pizzas do you have? 4.<br />We next move to one Pizza, and get 2.<br />The to "how many halves are in a half Pizza? 1.<br />Finally we move on to the quarter Pizza, and they quite naturally conclude that there is half a half pizza in a quarter.<br />I then say we now half to go back and find a procedure which will give me the answers we got.<br />Larry Cuffehttps://www.blogger.com/profile/00369944489322957884noreply@blogger.com
