This article offers an interesting tool for teachers to teach
mathematics, being both interesting to students and relevant to
their lives. The article brings to light real financial issues
in life placed in the context of appliances that all students
feel are important (TVs, VCRs, and stereos). Extension activities
could include collecting information from home about what appliances
are 'suspect', estimating home usage attributed to these appliances,
and annual costs due to these.
The article allows for class discussion in other key learning
areas such as environmental concerns and energy conservation.
Class discussion could also include answering the big questions.
