This presentation discusses two types of visual instructional materials: chalkboards and whiteboards. Chalkboards are reusable writing surfaces made of calcium carbonate where text or drawings are made using chalk. They vary in size depending on the classroom level. Chalkboards can be used to write, display information, organize games, and draw. Whiteboards are similar to chalkboards but are made of a material that can be written on with dry-erase markers. They are easy to maintain by wiping clean with a dry cloth or using isopropyl alcohol to remove leftover markings.

“rewriteable” school
