Abstract: The kinesthetic number line may be used for teaching numerical counting. A flat panel may have a number line image on an upper surface thereof. A longitudinal track may be disposed adjacent a longitudinal portion of said number line image. A plurality of orthogonal tracks may be in communication with the longitudinal track wherein each of the orthogonal tracks may terminate at a second end adjacent to one of a set of sequential numbers in the number line image. A ball may be movable in the longitudinal track and in the plurality of orthogonal tracks.

Abstract: The multiple line drawing aid is a generally U-shaped device or channel which has holes in one side member and a tension friction plate attached to the holding member opposite. The tension friction plate has slots on the edge which are located to correspond to the holes in the aperture member. A drawing instrument such as a dry erase marker is then inserted in each hole and pushed into the structure formed by the friction plate and face plate to retain the marker. The holes and slots then serve to hold the inserted markers when the users moves them across a drawing surface to draw parallel lines.

Abstract: The multiple pen holder and drawing aid is a generally rectangular device or casing which has holes in one side and retaining elements in the casing to hold drawing instruments such as dry erase markers, pens, pencils and similar instruments. The retaining elements and holes are arranged such that the drawing instruments are retained in the casing with the tip ends extended outwardly through the holes. The user may then hold the drawing aid in one hand to use to draw multiple parallel lines on a drawing surface. The casing has a top casing element and bottom casing element which are hinged relative to each other and latched for closure. Thus the casing may be opened in a clam shell manner for insertion and removal of drawing instruments.
