RE: Geometry - high school curriculum in 8th grade

Not an easy question. Depends on what "bright" means. Are the kids off
the charts or just good, solid math students? If the latter, I wouldn't
rush them into something. Let them learn the geometry of spatial
relationships. If you're thinking you have to do formal proof [and lots
of them], I would worry. Kids this age need to explore geometry --
Geometer's Sketchpad, Cabri [both 2-d and 3-d], and Cinderella 2 are all
wonderful tools that can lead to incredibly sophisticated thinking and
ideas. I would turn the kids loose.

Now, as for the truly bright kids, I think they need some appreciation
of proofs -- but again, they [perhaps more than the others] need to play
and explore geometry. They'll come up, with teacher guidance, with some
great ideas and won't be frustrated by the contrived proofs of a

The bottom line is really what you mean by a traditional geometry class.
I'm not sure that's for anyone these days.

have looked like in 7th grade. Was it filled with manipulations
[factoring, simplifying rational expressions, etc. -- the stuff of
ready for this -- though I'm not trying to doubt your students in any
way. Nor do I know about your school and its constituency. This makes it
a challenge to answer your question well. Again, however, I think that
algebra at this level can be very exploratory and get at some very deep
ideas that way.

Math students must be able to mature as math students. This requires
maturity in a great many other aspects of their lives.

I have been faced with this situation. Our solution has been to explore
algebra [we used Discovering Algebra from Key Curriculum Press in 7th
grade followed by a "traditional" algebra in 8th and geometry in 9th.

Just my thoughts.
