Maths detective: checking a game score

A mini detective challenge where children spot addition and subtraction while checking a game score.

Quick answer

Maths detective: checking a game score means using addition and subtraction to work out how many points a player has scored. You can spot maths in games, sports, and even in your daily life – it’s all around you!

Learning outcome

By the end of this page, you will be able to check a game score by adding and subtracting numbers to make sure it’s correct. Success signs:
  • You can add up points in a game.
  • You can subtract to check if a score went up or down.
  • You can spot maths in games without even realising it!
  • You can explain how you checked a score to a friend or grown-up.

Why this matters

You use maths every day – even when you’re playing games! When you play football, board games, or video games, you’re adding and subtracting points without even thinking about it. Learning to check your scores helps you become a maths detective and improves your number skills. It also helps you understand if you’re winning or losing, which makes games more fun.

How it works

To check a game score, you need to:
  1. Look at the points scored in each round or part of the game.
  2. Add them all together to find the total score.
  3. Subtract to see if the score went up or down.
  4. Double-check your maths to make sure it’s right.
Let’s imagine you're playing a fun game where you earn points for different actions. You might get 5 points for a goal, 3 points for a bonus, and lose 2 points for a mistake. To check your score, you add and subtract these numbers.

Examples you can see

Let’s try a real-life example from a football match. Imagine you’re watching a football game where:
  • Team A scores 3 goals in the first half.
  • Team A scores 2 goals in the second half.
  • Team B scores 1 goal in the first half.
  • Team B scores 4 goals in the second half.
To check the scores:
  • Team A scored: 3 + 2 = 5 goals
  • Team B scored: 1 + 4 = 5 goals
Now, let’s say you are playing a board game and your points change like this:
  • You start with 10 points.
  • You earn 5 more points.
  • You lose 3 points.
To check your final score:
  • Start with 10 points.
  • Add 5: 10 + 5 = 15 points.
  • Subtract 3: 15 – 3 = 12 points.
So, you have 12 points in total.

Try it as a mini adventure

Adventure: The Score Detective Challenge You are a maths detective who has been hired to check the scores in a big game! The game has 4 rounds, and each round has different points. You need to work out the final score for each team and make sure it’s correct. Here’s your mission: Round 1:
  • Team Red: 5 points
  • Team Blue: 3 points
Round 2:
  • Team Red: 2 points
  • Team Blue: 4 points
Round 3:
  • Team Red: 3 points
  • Team Blue: 1 point
Round 4:
  • Team Red: 4 points
  • Team Blue: 2 points
Your task:
  1. Calculate the total score for Team Red.
  2. Calculate the total score for Team Blue.
  3. Check if the final scores are correct.
Answer:
  • Team Red: 5 + 2 + 3 + 4 = 14 points
  • Team Blue: 3 + 4 + 1 + 2 = 10 points
You’ve solved the case! The final scores are 14 for Team Red and 10 for Team Blue.

Common mistakes

  • Mistake: Adding numbers in the wrong order.
    Why it happens: Children might not look carefully at the numbers and add them in the wrong sequence.
    Fix: Always go through the numbers one by one and double-check your addition.
  • Mistake: Forgetting to subtract when points are lost.
    Why it happens: It’s easy to get excited about earning points and forget about losing points.
    Fix: Remember to subtract when you see words like “lose,” “take away,” or “subtract.”
  • Mistake: Thinking that adding and subtracting are the same.
    Why it happens: Some children confuse the two operations.
    Fix: Practice with simple examples like “I have 5 apples, and I eat 2” (subtract) versus “I have 5 apples, and I buy 3 more” (add).

Parent and carer guide

As a parent or carer, you can help your child by:
  • Playing games together and asking them to check the score.
  • Using real-life situations like shopping or cooking to practice adding and subtracting.
  • Encouraging them to explain how they checked a score – this helps solidify their learning.
  • Not worrying if they make a mistake – mistakes are part of learning!
  • Practising with simple number sentences and using visual aids like counters or blocks.
It’s important to keep the activity fun and not make it feel like a test. You can say things like, “Let’s see if we can check the score together!” or “What do you think the final score should be?”

Practice questions

  1. Sam has 12 points. He earns 5 more points. Then he loses 3 points. What is his final score?
  2. In a card game, you start with 8 points. You win 4 points, then lose 2 points. What is your final score?
  3. A basketball team scored 7 points in the first quarter, 5 points in the second quarter, and 3 points in the third quarter. How many points did they score in total?
  4. You have 15 points. You lose 4 points, then gain 6 points. What is your final score?
  5. In a race, you start with 10 points. You gain 5 points for finishing first, lose 2 points for a penalty, and gain 3 points for a bonus. What is your final score?
Answers:
  1. 12 + 5 – 3 = 14 points
  2. 8 + 4 – 2 = 10 points
  3. 7 + 5 + 3 = 15 points
  4. 15 – 4 + 6 = 17 points
