Kind of cute for helping students to remember positive, negative, undefined and zero. Have the kids walk outside, and experience the different slopes. Walk them up to a wall and ask them to keep walking to experience undefined slope.

This is a game I play with my students to practice corresponding angles, alt. exterior, supplementary, same side interior. They must place feet in the type of angles I call out. (Simon says style)
