At the same time, I was ready and had worksheets ready for the students. We were just repeating prisms (cube and block). I also realized that it is better to have the preparation prepared on one sheet of paper. I had it on 3 papers and then, when you put the paper away somewhere, in the meantime it explains something, it loses an overview of which paper follows and where it lies at all.
