ABSTRACT:
A portable system for multiple educational activities includes multiple planks and connectors and allows for the arrangement of the planks and connectors in different configurations to enable use for a variety of activities. One of the activities requires four planks be configured in a square shape with the connectors attached to the ends of two of the planks thereby allowing sliding engagement with slots in the sides of the other two planks. A second activity requires two planks be attached at one end via a pivot joint which allows for variation of the angle between the planks. Also provided is a method for using the portable system.
