How To Keep Track Of Erasers

Do you want an easy way to keep track of erasers? This is the simple way I kept track of my erasers when I taught middle school art.  

How about using an ice tray that's color coded?

In the tray, there would be three erasers for the red group, the blue group, the green group and the yellow group. The color coding helps to keep track of which group was using an eraser.

When some one in the blue group needed an eraser, they took one of the blue dotted erasers. When they were done they put it back to the blue color coded spot.

When the class was cleaning up at the end of the period, it was easy to glance over to see if all the erasers were put back in their proper spot.

Pretty simple, huh!
