I'm trying to make a beamerbeamer presentation for a lecture that also contains some small exercises. So I needed TeX to create a page where there are just the questions with room between each of them for the answers, followed by a page where the answers are included. Now the empty space should be just as large as the answer will be, for a nice look. In
In addition I planned to give the presentation to the students some time before the lecture so they don't have to write down everything. Of course for this purpose I need a version of the presentation, where all the answers are left out.
I tried to create an environment using a boolean variable to specify whether the solutions should be printed or not. Now this would have helped to create an extra output for the students but would not have helped to hide the answer on one page and show it on the next. Anyways, my attempts on doing so by using the etoolboxetoolbox package didn't work at all.
I read about the package exsheetsexsheets and hoped it could help me but only gave me an error that the file tasks.stytasks.sty could not be found.
Has anybody experience with such problems?
