I was so upset right, before Christmas vacation, because someone “got’ me again. I had the little gifts on my desk that I was going to give to my students when suddenly two were missing. I have a pretty good idea who took it, ut no proof.
So, that’s when I decided to inventory my stuff. It took a little bit of time since I have about 100 little erasers, but I did it. That way, I know exactly what and how much of any one given thing I have in my classroom store. It keeps me in the know and my students who manage the store honest.
