My advice would be to not do it at all. I think the Giampieri is a great book, and one of the most useful things for developing technique. However, they are not particularly useful as lesson material. Their best use is for individual practice.
In any event, at least for my students, these exercises would not be particularly appropriate for pre-college age students. I have a number of things that I would recommend before getting to Giampieri, including the Milde Studies in Scales and Chords.
Playing them certainly won’t hurt you, but it might be a better use of your time to work on more standard studies or repertoire. If you aren’t completely familiar with such things as all the Weissenborn, the Milde Concert Studies, etc., I would recommend working on those.
But, don’t spend too much time trying to anticipate what your new teacher is going to assign to you. He or she will have plenty of ideas about that.
