  1. Odometer Task

  2. MANIPULATING CIRCULAR OBJECTS

  3. OBSERVING THE RESULTS What do we notice? By establishing the perimeter/diameter ratio, we approximately obtain the number Pi (3,1416). It is not necessary to show the formula P=2R, but useful to make others understand that there is a mathematical relationship between all circles.
