cooperative learning classroom the desk This drawing shows the durable yet low cost construction of the desk. The leg tubes are extruded in three different lengths for different grades. The desk supports and feet of the legs are the same piece for low molding costs. The unique shape of the legs allow freedom of movement under the desk working from either side. The holes in the worksurface are used to mount the center chalkboard or possible other tools to be developed. The polypropylene legs are taken back by the manufacturer at the end of their life to be recycled into another desk. Enough about the desk tell me about the chair, chalkboard, or configurations
