Being a teacher, I use multiple whiteboards every day at school. I don’t know what we would do without them now. Years ago, we used chalkboards and had to deal with messy chalk dust at school. Back then, we had no idea about a whiteboard, whiteboard mount, whiteboard marker, or whiteboard eraser. I wonder how many people’s allergies were affected by all that chalk dust? I’m so glad we have whiteboards today!
