Absolute Value equations: “You are there” relevance

One of the most motivating experiences I can sometimes create for my students is a feeling of what it can be like as an adult in an interesting career.  The little extra time that kind of activity monopolizes is well spent.  The idea of absolute value is found everywhere something is being built or produced:  typically called tolerance range.  This activity provides students a little experience with the field of metrology.  I argue such experiences are becoming a social justice issue.
