For what it's worth: some commments regarding the above. I've always

found it rather strange that in the USA, geometry in the high school is

restricted to only one year. In South Africa, geometry is taught in

alongside algebra, trigonometry and calculus throughout the high school

curriculum starting in the Grade 7 with tessellations, enlargements,

informal Euclidean and transformations with the first introduction to

proof in Grade 9, and then only in the context of explaining why certain

interesting surprising results are true (A complete aiomatization is not

done). Starting with some local axiomatization in Grade 10 this is

extended to a more complete axiomatization in Grades 11 & 12. Trigonmetry

is also started in Grade 10 and in Grades 11 and 12 some Analytic

Geometry is also done.

I certainly don't believe it is a good thing to artificially

compartementalize math - I believe students benefit more, learning more

meaningfully by seeing the relationships between the different topics

within math and how they can cross-fertilize each other...
