Gadgets on standby eat power




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. Should we turn off our appliances? What needs to be considered? (e.g., some VCR's need to be reprogrammed when they are turned off)
