Love, Fifteen, Thirty

Three short lessons for tennis watchers: reading the score, why a small edge on points becomes a big edge on matches, and why nobody is sure where 15-30-40 came from.

For grown-ups, from what ScorePals teaches children at Spark & Anvil.

  2. Lesson 2Edges compound

At the table · Two or more, ages 6 and up

Keep the score on the sofa

You'll need: A tennis match on TV or a backyard rally, paper.

  1. One person calls the score aloud after every point: love, 15, 30, 40, deuce, advantage.
  2. Another keeps a tally of who won each point.
  3. At the end of a game, count the points each player won and check them against the calls.
  4. Talk about a game where one player won more points but lost the game.
Where the numbers came from

A little history, and what nobody knows

Fifteen, thirty, forty

Counting a tennis game as 15, 30 and 40 goes back to medieval France. One story says the score moved a quarter of the way round a clock face, and that 45 was later cut to 40.

Where the numbers really came from is not known; the clock story is a guess.
