An activities module is positioned on a support surface, such as the floor of a room, to provide activity stations with horizontal work surfaces. The module includes an upright post member that has at least two vertical grooves. A flat panel has an opening sized to receive the post member when the flat panel is oriented horizontally, and upright partition panels are provided corresponding to the vertical grooves in the post member. Each partition panel has an inner edge fitted into the groove, an outer edge and a bottom edge that rests on the support surface. The partition panels each have a slot to receive the flat, horizontal panel, and fasteners secure the module together. A second flat, horizontal panel may similarly be mounted below the first flat panel, and a third flat, horizontal panel may provide a shelf or bench. Preferably, the first flat panel is circular and the upright post is located centrally thereof; four partition panels are spaced around the center post to divide the module into four activity stations.
