The usefulness of this tool for teachers is immense, particularly for geometric images, as seen in the poster, 'Triangles', where the image provides clarity to the subject matter in a concrete way.
Many examples of mathematical art doesn't contain an image at all. These works are purely visual aid posters that are meant to inform, rather than remind or provide a particular insight. These works are generally fairly plain and provide the bare minimum of information, without context or aesthetic appeal. Works like 'Multiplication Table' are typical in this sub-category of formulaic prints.
Math posters for younger audiences have more graphic qualities. These works typically focus on recognizing the form of various numbers. For example, Megan Meagher's mathematical image, 'Kid's Room Numbers' uses bright colors and a variety of shapes to make the subject more interesting, as well as educate and enlighten young pupils who may be unaware of the meanings within the symbols.
