Introduction: 1) Chalk boards still have plenty of benefits today despite the relatively recent advance of white boards: chalk boards are available in a variety of sizes and styles, can be mobile, mounted to walls, or hand-held. 2) Chalk (and dust-free chalk) is now available in a variety of colors, so you\'\'re able to make your presentations bold and bright 3) The invention of dust-free chalk plus test results proving that even standard board chalk is free of toxic substances (scroll down for more information) eliminates major concerns about using chalk 4) Chalk generally lasts longer, doesn\'\'t dry out, and is less expensive to restock (easier on your budget) than whiteboard markers, particularly for high velocity users. Chalk can be washed out of clothes and off skin much easier than dry-erase markers.
