Each family to make as many copies of the activity book, workbook, or set of student pages as they need for their own family without infringing copyright. For example, if you purchase a workbook for Abby Jones, her family can make a copy of that workbook for her younger brother, Sam Jones, which he can use when it is his turn, without infringing copyright. But the Jones family can't make a copy for Sam's best pal, Fred Smith--that would be copyright infringement.
