If you add \addtocounter{framenumber}{-1} in a TeX inset (formerly known as
ERT) in the body of each instructor-only slide, the student slides will be
numbered as you wish. This will not prevent the instructor slides from
displaying slide numbers; it will just prevent those numbers for advancing.
So, for instance, if you use a theme that displays current slide number and
total number of slides in the footer, you will obtain something like the
following:Student slide (1 of 4) Student slide (2 of 4) Instructor slide (2 of 4) Student slide (3 of 4) Instructor slide (3 of 4) Instructor slide (3 of 4) Student slide (4 of 4) To suppress the footer (and hence the page numbering) in the instructor slides, make them PlainFrame rather than Frame AND put in the LaTeX command to tweak the frame number.
