I haven't taught geometry for seven years, but when I did there was almost no arithmetic until the second semester. And the bulk of that came in a unit that dealt with areas, surface areas, and volumes (there was also a little arithmetic in a unit that introduced right triangle trig functions). What I noticed was that those students who had the most difficulty with logic and proofs also had difficulty with computations and were the first to grab their calculators (yes, I allowed them).

I have taught geometry without using arithmetic. On the other hand, I see much of algebra as an abstraction of arithmetic. Perhaps that is my blind spot here, but I cannot envision explaining much algebra without a solid arithmetic base to build upon. I certainly have never seen it done at either the secondary or collegiate levels. (And it is probably pertinent to reiterate that at my alma mater, secondary math ed students are in the math department, not the College of Education. All but the student teaching class involved straight math majors and math ed majors. That was the primary difference in the two programs.)
