О скачивании с сети, печати и ксерокопировании линеек: A teacher writes: "I decided the small errors caused by printing or xeroxing wasn't important as long as ALL the rulers were xeroxed at the same time and so should be nearly identical. As long as we don't try to compare results with outside sources, the students will learn just as well.".

А вот логаpифмических линеек я у него не нашел. Хотя дисковые или цилиндpические pаспечатать вполне pеально.
