I remember joking last year about DS' pre-algebra text. It was ancient in age and ratty in condition and has been the same textbook used by our district for GT students for eons while the regular students have received at least two or more changes/upgrades in textbooks. Nevertheless, DS' pre-algebra text was a good book geared toward GT students.

However, DD will be taking pre-algebra next year and the district is switching to UCSMP (University of Chicago School Mathematics Project). Does anyone have an opinion/knowledge of UCSMP?
