A dry erase panel assembly for use as a teaching aid includes a first panel with a top edge, a bottom edge, a left edge, and a right edge. The first panel includes a writing section that is adapted to eraseably receive markings thereon. The panel assembly further includes a second panel with a top edge, a bottom edge, a left edge, a right edge, and a holding section. The second panel is secured to the first panel along the left edge and the right edge, whereby the holding section is spaced from the writing section to define a gap therebetween adapted to receive an information template.
