Learning outcome

By the end of this page, you will be able to count the number of games in each set and the number of sets in a tennis match. Success signs:
  • You can say how many games are in a set
  • You can add up the sets to find the total match score
  • You can play a pretend tennis game and keep score
  • You can use numbers to describe a tennis match

Why this matters

Tennis uses maths to keep track of how many games and sets players win. When you watch tennis, you see players counting their wins. Understanding this helps you follow the game better. It also helps you play tennis games at home or with friends. You can also use these maths skills for other games or sports where you count points or rounds.

How it works

In tennis, a match is made up of sets. Each set is made up of games. To count the maths in tennis:
  1. Count how many games are won in each set
  2. Add up all the games from all sets
  3. Count how many sets are played in the match
  4. Use numbers to show the score

Examples you can see

Let’s imagine a tennis match between two players, Alex and Bella. Set 1:
  • Alex wins 6 games
  • Bella wins 4 games
Set 2:
  • Alex wins 3 games
  • Bella wins 6 games
Set 3:
  • Alex wins 6 games
  • Bella wins 2 games
How many games did Alex win?
  • Set 1: 6 games
  • Set 2: 3 games
  • Set 3: 6 games
Add them up: 6 + 3 + 6 = 15 games How many games did Bella win?
  • Set 1: 4 games
  • Set 2: 6 games
  • Set 3: 2 games
Add them up: 4 + 6 + 2 = 12 games How many sets were played?
  • 3 sets
What is the match score?
  • Alex: 15 games
  • Bella: 12 games

Try it as a mini adventure

Adventure: Tennis Match at Home You and a friend are playing a pretend tennis match. You decide to play 3 sets. Each set has games. You win 5 games in the first set, your friend wins 7. In the second set, you win 6 games, and your friend wins 4. In the third set, you win 3 games, and your friend wins 6.
  1. How many games did you win in total?
  2. How many games did your friend win in total?
  3. How many sets were played?
  4. Write down the match score like a tennis scorecard.
Answer:
  • You won: 5 + 6 + 3 = 14 games
  • Your friend won: 7 + 4 + 6 = 17 games
  • 3 sets were played
  • Match score: You 14, Friend 17

Common mistakes

  • Mistake: Adding the wrong numbers. For example, thinking 6 + 4 = 11.
    Why it happens: Confusing numbers or not checking the addition.
    Fix: Count on your fingers or use a number line to double-check.
  • Mistake: Forgetting how many sets are in a match.
    Why it happens: Not knowing that a match can be 3 or 5 sets.
    Fix: Remember that tennis matches can be 3 sets (best of 5) or 5 sets (best of 9).
  • Mistake: Mixing up who won how many games.
    Why it happens: Getting confused during counting.
    Fix: Write down the scores as you go to keep track.
