No. Chalk is a soft carbonate sedimentary rock whereas slate is a fissile rock with a pronounced cleavage formed by the metamorphism of fine grained sedimentary rocks containing clay minerals. Chalk (the soft white mineral used in marking on a slate or blackboard) is actually now commonly made from gypsum but in the past was actully composed of calcitic chalk.
