Abstract: Described is a convertible item that is portable and that can be easily folded into a playing field through the use of one or more pop-up elements. For example, the convertible item is a substantially flat item that can transition between a first state, in which it is substantially flat, to a second state, in which the pop-up element is affixed in an upright position. In the second state, the convertible item operates as a playing field to allow users to play on its surface. For example, the playing field includes goals (in a soccer or hockey aspect) or can be formed to include a ramp (in a toy skateboard aspect). The convertible item is any suitably flat item, such as a folder for papers, or a greeting card. Thus, it can transition between a folder or card, to a playing field.
