Two different science themed class period labels. Periods are labeled 1-9 or A-I (in case your school is weird and letters your periods like mine. The file includes two different icons for both the numbered and lettered labels.
These labels can be printed small to for bins and folders or larger for labels posted on a Bulletin board or whiteboard.
If you need your periods labeled in a different way please let me know and I can make the adjustments needed.
