A student is responsible for collecting sheets handed out in class for those students who are absent. This is what is often said to me as I'm handing out the sheets. I've always corrected them by stating that "need" is a state verb and in this instance should be in the simple present. It's an immediate need.
My colleague (a native-speaker), however, just argued that you could very well say "would need" in this context.
Is "would need" acceptable in this context and is the reason because it's conditional?
I would need 3 more sheets (because 3 students are missing and I have to put 3 in the missing-student's binder for them.)
