Sixth graders discuss sports. They are asked to name an Olympic sport that involves team as well as individual competitions. They then are asked what they know about scoring in gymnastics events. They are told that judges score competitors starting with 10 as a perfect score and subtracting decimal amounts for small or large mistakes or for falls. They use scores from a national gymnastics festival held in July 2000 to practice subtraction. Consider having your class look up more recent Olympics scores to use in this exercise.
