Unfortunately at this point I know of know way… I keep track of which week it is outside the program for those things that aren’t done at least once a week.
You can close the assignment temporarily by clicking the triangle left of the assigned lesson/chapter/etc in the daily plan. This assignment will then not show up when printed. When scheduling the resource, make a note in the custom study method tab to remind yourself that the resource is for every other week. You can also make a note in the divisions that the assignment is Week 1, Week 3…or perhaps put in the dates you want it scheduled in the divisions. Remember that you can edit the divisions anytime and can add dates/lessons/notes as you go. I am slowly scheduling my daughter’s algebra and adding lessons in the divisions gradually. The boys following her will have a completed lesson plan when it is their turn to use the resource. That is why I like the organizer. It is flexible and can be gradually built…not quite set in stone, yet with a reasonable amount of organization and accountability. I hope that helps.
