The problem likely lies with the chalk itself. A lot of chalk you buy today, especially cheap chalk, is too hard to use on chalkboards with any kind of good result. Try a different brand of chalk, one that is softer.
They didn't. Most Native Americans didn't have writing systems prior to the arrival of the Europeans.
victorian children wrote with charcoalI think you will find that for school work they used a chalk and board, and for writing on paper, a quill pen and ink, but if you were poor and in a village school you would only use chalk
The biggest advantage of a chalkboard is that it provides a fairly inexpensive way to write on the wall of a classroom to be seen by all students. Chalkboards have many disadvantages however, including the terrible sounds they make when scratched or touched by some things and the lack of flexibility and interaction offered by a dry-erase board or a SMART board.
I imagine anything prisoners of any other time used. ink, lead, chalk, blood, mud onto the ground, wood, paper, clothing, tattoos, rocks

A chalkboard is a piece of slate on which to write with chalk and is named after the color "black".

Chalk
Chalk is made of calcium carbonate, a soft mineral that leaves a visible mark when drawn on a rough surface like a blackboard. When drawn on the blackboard, chalk particles rub off and stick to the surface due to friction, creating a visible line.
It is easy to write on a rough blackboard. The friction between the chalk and the rough surface is what allows the chalk to leave behind the chalk dust that we see. Actually it would impossible to write on a theoretically smooth blackboard. Without the friction, the chalk would not leave any residue!
To write and draw with chalk for educational, personal, entertainment, or commercial uses.
Blackboards are typically made of a material that is softer than chalk, such as slate or porcelain. When you write on a blackboard with chalk, the friction between the chalk and the board causes the chalk to wear down and leave behind tiny particles of sand or abrasive material embedded in the chalk. These abrasive particles then scratch the surface of the blackboard as you write, creating marks that can be difficult to erase.
Chalk is softer than the slate (real or artificial) used on blackboards, so it will flake off as you write. Granite is harder than slate and will not flake, but rather cut into or mark the slate permanently.
Well you see, as the chalk rubs against the blackboard bits of it get left behind, showing you what your teacher thinks your cursive should look like, or a new trick when dividing big numbers.
There is no difference between a chalkboard and a blackboard; they are two different terms used interchangeably to refer to a smooth, dark surface on which you can write with chalk.
Assuming you mean chalk, as in what you write with on a blackboard, then the two ways are "la tiza" and "el gis." El gis is used in Mexico.
M.Hamel wrote "Vive la France!" on the blackboard before dismissing the last class.
