My students also have trouble with exercises like that. I found a more structured and precise way to develop the sense of 3d space and practice the basic shapes. It helped them to go through the repitition and gave them specific goals along the way, and the structure makes sure that they are not repeating shapes/positions that they already know well, which saves time. It also provides instant feedback to fix mistakes. If you are interested, I made it available to the public recently and think is a good addition to the other exercises on this site: Practice Kit
