I am very fortunate that my classroom is right next to an exit door that is used for fire drills. I am able to take my class outside at a moment's notice to do things like walk through the steps of human coordinate graphing.
For the x coordinate students walk right for positive and left for negative. For the y coordinate they move forward (up) for positive and backward (down) for negative. The whole class moves together and counts aloud as they move. I make sure we throw in some zero coordinates so they realize that zero means they do not move.
By sixth hour (my last class) the students were a little more wound up so I actually allowed some of the boys to leapfrog their coordinates. They loved that!
I really feel this
hands feet on activity helps struggling students to get a better grasp of this concept. All the kids love going outside and moving around while doing math. I always tell my students that my math class is not a spectator sport, but full contact learning. :)
