In the subtraction strategy constant differencing explain how it works using the following problem: 


500-99    =    ______ - 100 

In the constant differencing you make it easier by keeping the difference or the amount subtracted the same.  For example, in this problem you add one to 99 to make it a nice easy 100 and to the 500 you are going to take one away to keep the difference the same.  The answer would be 499.

In the finding the difference strategy we jump ahead on the number line.  Show your work to solve the problem 2005-1999 = 

The answer would be 6.  Students should show work by jumping ahead.
