Seems the negatives are newsworthy :) The comments have some
interesting ideas, too.

I draw a horizontal line and call it ground level. A pile of dirt can

be x feet above ground level (positive). A hole in the ground can be x

feet below ground level (negative). You can add a positive value by
filling the hole and/or making the pile taller. You can add a negative

integer by shoveling off of the pile and/or digging deeper.
Subtraction problem are converted to addition. For subtraction, the
mantra is "cross the line [change from subtraction to addition] and
change the sign [of the second integer]"
