Planning and organising

You have the job of organising a table tennis league.

  • 7 players will take part
  • All matches are singles.
  • Every player has to play each of the other players once.
  • There are four tables at the club.
  • Games will take up to half an hour.

Calculating Body Mass Index

Exploring and discovering

This calculator shown is used on websites to help an adult decide if he or she is overweight. What values of the BMI indicate whether an adult is underweight, overweight, obese, or very obese? Investigate how the calculator works out the BMI from the height and weight. Important: the index is intended for adults and is not useful for young people who are still growing - pupils should not use this to compare their own BMI scores!
