Tom, the expectation is that they will take Geometry next. The chances of this population making it to Algebra 2 are slim to none. We do have an elective course for precollege math that focuses on the kind of math students need for CUNY college placement tests  basically, trying to avoid remedial math placement in college (or needing less of it). That's a common third course for the students in this progression. The other elective option for the third course is Business and Personal Finance, which is taught to juniors and seniors as a third or fourth math course and is often used for students who need another math credit and have not had much success in getting that credit in the usual algebra and geometry classes.
Nick, thanks for the top 50 worksheet. In taking a first look at it, I am seeing that there are a few things I will have to review for myself before I feel comfortable teaching them again. This was a lot of work and beautifully arranged. Thanks for sharing it.
