I have found my "thing" when it comes to excursions. Trip packs have essential information, but can be quite fiddly and frustrating when you quickly flip past a sheet your trying to find. My best solution has been to use the small Post It Notes as index tabs. An easy and effortless quick reference system! Boom. To prevent the pages being messed up (or blown away on an outside excursion) I hole punch and use two ring clips to keep it all in place. Our Grade level aid is a star, and she also puts them in a plastic water proof folder. Voila!
