A method for instructing mathematics includes providing a work surface to a visually impaired student; providing a plurality of movable elements for use in connection with the work surface, each of the movable elements comprising on a front surface thereof at least a portion of a visible mathematical symbol readable via eyesight, each of the movable elements further comprising Braille indicia on the front surface thereof corresponding to the at least a portion of the visible mathematical symbol, each of the moveable elements being movable to any position on the work surface; and having the student arrange a plurality of the moveable element on the work surface to form a standard mathematical expression wherein the mathematical expression comprises multiple lines set forth in a vertical arrangement.

Teaching aid device and method of teaching

A device for instructing mathematics includes a work surface and a plurality of movable elements. Each of the movable elements includes, on a front surface thereof, at least a portion of a visible mathematical symbol (including numeric and nonnumeric symbols) thereon readable via eyesight. Each of the movable elements further includes an attachment member on a rearward surface to attach the element to the work surface. The attachment member preferably allows the element to be removed from the work surface and to be slidably positionable to any position on the work surface once attached thereto. The device can further include a frame around the work surface. Preferably, the frame defines a boundary for positioning of the movable elements. In one embodiment, magnetic attraction is used to maintain the attachment member in movable connection with the board.
