Today I wrote my name on the chalkboard and immediately started scratching (like a mosquito bite). I totally forgot that I'm allergic to chalk. You're probably thinking---really, a teacher allergic? That's classic.
Sad but true.
During my 4th grade student teaching I discovered this. I kept braking out in hives and scratching madly. I went to my doctor because my face was raw and red. The doctor couldn't figure it out either. I was told it could be my cat/carpet/pollen/bug bites,etc. When I left the school, it cleared up within a week and that's when I figured it out. (Actually, I forgot about it until now.)
I'm glad I have a Smartboard to use instead!
