I will be teaching first grade. I'd like to set up a system with a "sharp pencils" container and a "dull pencils" container. Students simply put in the dull pencils and take a sharp one. I like this idea for two reasons: it cuts down on the noise of sharpening in the class (I or a student will sharpen at the end of the day), and it cuts down on wear and tear on my electric sharpener. My concern is with students who bring in fancy pencils. If they are putting them in a "dull pencils" container, they may not get it back. I don't want to prohibit them from bringing in fun pencils. Should I have them sharpen two in the morning, and then use the bins throughout the day if both of their pencils break? Thanks for any suggestions!
