They all use to be black, when they changed them to green, they should have been called green boards.

Because the original ones were black. Then someone figured out that a green surface was easier to read from a distance. I remember the black blackboards in my elementary and high school - I graduated high school in 1967.

Early blackboards were made from pine lumber and covered with a mixture of egg white and carbon from charred potatoes. Hence the name BLACKboard. Teachers and students wrote with chunks of chalk and erased with cloth rags. When slate boards became available, teachers used cylinders or white, soft chalk and a felt eraser. These blackboards and slate boards were laborious apparatuses, and the accompanying chalk dust was the bane of all teachers.

well, back in the olden days, when i went to school (in the 80s) the chalkboards were made out of slate which was black. My HS was built in the 50s, and they still used (black) slate back then. However, some of them were replaced by green and even blue boards. But most of them were the original black slate.
A lot of schools now just use the white "dry erase" boards. Eventuallly they'll do away with the whole "writing on the board" thing. Then you'll tell your grandchildren," back when I was a kid, they used to write on a big board!" And it wont matter what color it was. You will be old. God, you're making me feel old even having to answer this question, you young whipper snapper!

Because back in the day (as in the "good old days") - they were always black. Then they did change colors and were still chalkboards. Now mostly we find whiteboards in classrooms and they don't even use chalk, yet they are still often called blackboards out of habit.

Blackboards was once created from slate, an very virtually black gray mineral. actually, they're (or was once) generally stated as slateboards. Small hand-held ones have been in basic terms stated as slates. while blackboards began being created from a green ceramic or ceramic-like cloth, their historic call in basic terms accompanied them. The question i could have is why are the ceramic boards green?

back in the day (ahem), blackboards (or chalkboards) were made from black slate. kinda funny that some call these green composite fiber boards "blackboards" even worse when they refer to white formica as blackboards.

The original blackboards were made of slate, wayyyyyy back in classrooms in the 1800's.
The name just stuck for innovations and changes to the tool years later.
