The Blue Book mentioned gets a lot of love from people - I've never been as much into it though. With our varsity group we've tended to have more time on Region Etudes/Chromatic Scale in the fall to fulfill some of that need, and then focused on teaching through music selection.

With our NV group (we're a 1C as well) I discovered the 'Making Music Matter' books that Manhattan Beach put out. The 1st book that's meant for beginning students should never be used for beginners, but it's perfect as a 2nd year book for that group. (It moves recklessly fast on things for beginners!) For that second group it's been great for a refresh on notes, technique, throws harmony at them from the eighth number, and generally helps with sightreading prep too. Might be worth a look for your needs there too.
