After creating a new addition problem, slider Move Bunny! can be dragged with the
mouse causing the bunny to move along the number line. Starting at 0, the bunny moves
according to the sign of slider a’s value, turns around once it reaches the corresponding
value on the number line (if necessary), and continues corresponding to the value of slider
b, ending at the position of the solution to the addition problem.
Since this dynamic figure is intended to be used by the teacher, it doesn’t contain any
instructions for students. In order not to confuse students, it was exported into a webpage
and it doesn’t display all portions of GeoGebra’s user interface. This applet could be
used to introduce the concept of integer addition on the number line or to check students’
answers to addition problems by dynamically visualizing the process using the picture of
the bunny.
