[quote=Anonymous]The difficult concept is that you can represent an unknown with a symbol, on which you can then perform additional operations. One exercise I found useful is to simplify down to something really easy, like "You have c slices of cheese pizza. I give you one more. How many do you have?" At some point the child will begin to see that if c can represent a number of slices, "c+1" is also a number of slices. Then you say, now you have "c+1" and I gove you one more. Then you guide them in simplifying (c+1)+1 to c+2, since they know the associative property of addition.[/quote]
