Using a Gigabot3+ in HS education - how do you use this fabulous product?

I am new to 3D printing and have inherited a Gigabot 3+ that was ordered and used pre-COVID.  I work at an alternative education campus where we are focused on project/problem based learning and building digital skills in our students who "don't do school" (for numerous reasons).  I am looking for suggestions on how to build beginner and intermediate skill sets so that learners can be independent as they explore the world and solve problems.   Thanks!
