Learning Wall Charts are large graphics or posters intended to be hung on a wall as a teaching aid or source of information. Another way, a wall chart is a large poster that frequently displays information for educational purposes. Wall charts have been around since the 1840s. Learning Wall Charts serve various purposes, including illustrating concepts or things, demonstrating processes, distinguishing between similar things, capturing interest and stimulating emotion, etc. It is critical to have qualified teachers. A competent teacher with good textbooks but no teaching aid (wall charts) is analogous to a carpenter with a good tack hammer but no nails.
