Organizing K4 curriculum

For those who have used COAH’s K4 curriculum, would it be better to organize the items by file name or by the week they are used?

I’d love to hear what others did as well, but here is how we did it…

I say do what works for u but for me personally with LOTW I did it by letter easier to find and use… doing it by week may be more time consuming up front but at least in a pinch like vacation or something if it’s done by week u can just grab that folder and go… I do believe In a video Erica stated she did it by items not weeks like all the do a dot pages for LOTW in a folder all the dot to dot in a folder etc
