It is the markers that I am a maniac about. They are the item I detest replacing the most (way too costly when those back-to-school sales are over!). About two years ago, I found a system that worked perfectly and kept me from having to replace a single marker for the WHOLE YEAR!
It’s actually really simple…all we do is keep two of each color in one of the baskets. The students know the supplies aren’t cleaned up until there are two of each color in the basket. It makes all the difference in keeping track of the markers and it’s been great.
