old work stuff needs to go

As a teacher, we hoard all kinds of teaching supplies.  Last weekend I went through a cabinet in the hallway that housed OLD teacher editions of textbooks (copyright 1993) and associated supplemental materials.  We are in the early stages of adopting a new textbook and these are at least 3 adoptions ago!  I couldn’t tell you the last time I looked at them.

The text bank book even mentions that IF you have a computer to contact them and they will send you a disk with the text questions.  I’m assuming it is a 3.5 floppy!

So here are the pictures of all the supplemental materials I got rid of.  The actual teacher editions I took back to school just in case anyone wants one. (doubtful, but you never know)

Why do we keep things like this??  Any other middle school science teachers have these still?
