It depends on what you mean by βtheseβ. If you are referring to the sticks of chalk used for writing or drawing, then yes, we can say they are chalk, or at least they are made of a similar substance. However, if you are referring to the type of soft white rock that is composed mostly of tiny fragments of the calcite shells or skeletons of plankton, then no, we cannot say they are chalk, because they are not natural rocks, but manufactured products. Chalk is a fine-textured, earthy type of limestone distinguished by its light color, softness, and high porosity. Chalk is also the name of a series of strata consisting mainly of chalk. I hope this helps. π
I would say it is a physical change the chalk is being reduced to a smaller size. It still remains chalk.
