General (and simple) Directions:  
  • Be sure that the students have chosen the arrow in the upper left hand corner of the screen.
  • Be sure that the screen is maximized so that the tabs at the bottom of the screen are visible.  (The middle box at the right is showing a screen in maximized view.)
  • Use the "sliders" on the page to control the size of m (the slope) and b (the y-intercept).   When a line is drawn, "grab" (by clicking on) a Ski Bird  graphic and place him on the line to reinforce the concept being discussed.
  • To end the exploration, choose FILE - CLOSE.  When the box asking if you wish to "Save Changes" appears, choose NO.  This will keep the file in the same state as when you started working.  None of the students' changes (or messing) will be saved.
