I agree with the many responses stating weariness of the constant rehashing of the same agruements-basically a dislike of the nctm standards. Since that is what this list is about, maybe they could find a more receptive audience elsewhere. Maybe if we ignor them they will go away.
Those who are trying to implement the standards, and/or other math refrom so mathematics can become a pump, please don't unsubscribe! Let's sharre our efforts.
I recently taught a (roughly) 6 week unit to my 8th graders called Home Improvement. This was written by a friend who has written many excellent "replacement units". This unit used the spreadsheet to help build an understanding of algebriac concepts. the studetns were given the context of being interior designers. They had to make designs for a variety of clients, using the spreadsheet to determine labor and material costs. My students were extremely engaged. I was amazed at how adept they became with the spreadsheet in a very short amount of time. If you would care to further discuss this, email me firstname.lastname@example.org.
