When you take 6 feet and describe it as 72 inches, there's no change, because, When you take 6 feet and multiply it by 1.5 , you change it, because 9 feet is not. This will lead the child to look at the solution, which is 4 and to add 3 more to the solution in order to get X. A transformationis a process that manipulates a polygon or other two-dimensional object on a plane or coordinate system. Change definition is - to make different in some particular : alter. In the example provided above, the children can see that the net change is - 3, which means that X must have 3 more than the solution's answer so that the 3 can be taken away or subtracted.
