Subject: Re: Front End Estimation

Do you believe that a childs teacher is doing their job if the child
comes up with an answer of 3,112 when they just got done adding
numbers of 8,221, 7091, 1089 and 5,984? There is no use for fee. The
only check needed for this example is to notice that there is only one
of four numbers added that is lower than your answer! Mistakes are
mistakes, but in your example its a lack of caring. And thats a
problem the teacher needs to recognize and  help the student with.
