"Mrs. Hughes!!! My black marker is missing! Waaaahhhh (Snooki voice)."
"Mrs. Hughes, my black marker is dead."
They all assumed I had a secret-magical-endless supply of black markers somewhere. Not.
Here's my fix:
Expo dry-erase markers! Or any off-brand version. Expo's were on the kid's school supply list and in abundance around our room. So, we used them for black marker replacements. You can buy them in bulk (skinny or fat tips) instead of buying a pack of markers for one black. I also used these all the time when I made posters. I like the using Expo's and the Mr. Sketch smelly ones (although I have a problem with those... especially the purple one... mmmmm delicious) a little more than Crayola. A darker black.
Mr. Sketch now sells bulk packs of black too!
