Tell your teacher you lost the folder.
Why would you do anything else?

Either that, or find the folder.

Tell the teacher of the class you have before math you need to go to the bathroom. Come back and him you have diarhea and need to go to the nurse. In highschool that's an automatic ticket home.

So whats she gonna do? Expel you? Honest really is the best policy in some cases.

She'll probably give those notes to you if you ASK.

I guess your right......Has anyone ever lost a binder or fold full of notes before?

Tell them a Math addict stole your homework at knifepoint and you need the rest of the day off to recover.

First thing in the morning you go to the head of the maths department and tell them what happened and say that you are really worried about how it will affect your grades and make sure you look really worried & anxious.

I'm sure you're not invalid who's incapable of copying from a worksheet.

I guess, the very first thing, would be to make sure you lost it, are you sure you lost it? If not, think about the places it could be.

I lost it, it's somewhere in school....I think.....I hope

I lost a Chemistry notebook in 11th grade. We kept all our homework and stuff in there and nothing was graded until we turned it in at one point during each quarter. I had to redo all the assignment and it sucked.
