Maths in basketball: score differences
Work out how many points a team is ahead.
Quick answer
You can find out how many points a team is ahead by subtracting the other team's score from your team's score. For example, if your team has 24 points and the other team has 17 points, your team is ahead by 7 points.
Learning outcome
By the end of this page, you will be able to work out how many points one basketball team is ahead of another team by using subtraction.
- You can subtract two numbers to find the difference between them.
- You can use a number line or counting to find how many points one team is ahead.
- You can solve problems about basketball scores using subtraction.
- You can explain how you found the difference in points between two teams.
Why this matters
Knowing how many points a team is ahead helps you understand how the game is going. It's useful when you're watching basketball, playing it, or even when you're just talking about it with friends. It helps you know if a team is winning, losing, or tied. It's also a good way to practice subtraction, which you use in many other parts of maths and everyday life.
How it works
Subtraction is used to find the difference between two numbers. When you want to know how many points one team is ahead, you take the higher score and subtract the lower score. It's like counting backwards from the bigger number to the smaller number.
- Look at the scores of both teams.
- Find the bigger score.
- Subtract the smaller score from the bigger score.
- Write down the answer – this is how many points the team is ahead.
Examples you can see
Let's imagine you're watching a basketball game with your friend. The scores are:
- Team A: 32 points
- Team B: 25 points
How many points is Team A ahead?
Step 1: The bigger score is 32.
Step 2: The smaller score is 25.
Step 3: Subtract 25 from 32.
Step 4: 32 – 25 = 7
So, Team A is ahead by 7 points.
Another example:
- Team C: 41 points
- Team D: 48 points
How many points is Team D ahead?
Step 1: The bigger score is 48.
Step 2: The smaller score is 41.
Step 3: Subtract 41 from 48.
Step 4: 48 – 41 = 7
So, Team D is ahead by 7 points.
You can also use a number line to help you:
For 32 – 25, start at 32 and count back to 25:
32 → 31 → 30 → 29 → 28 → 27 → 26 → 25
You counted back 7 steps, so the answer is 7.
Try it as a mini adventure
Imagine you're a basketball coach and you're keeping track of your team's scores during a game. You have a score sheet and you need to find out how many points your team is ahead after each quarter.
Quarter 1: Your team: 12 points. Opponent: 8 points.
Quarter 2: Your team: 21 points. Opponent: 15 points.
Quarter 3: Your team: 30 points. Opponent: 27 points.
Quarter 4: Your team: 42 points. Opponent: 38 points.
How many points is your team ahead after each quarter?
Quarter 1: 12 – 8 = 4 points
Quarter 2: 21 – 15 = 6 points
Quarter 3: 30 – 27 = 3 points
Quarter 4: 42 – 38 = 4 points
Your team is ahead by 4, 6, 3, and 4 points in each quarter.
Common mistakes
- Mistake: Subtracting the bigger number from the smaller number.
- Why it happens: It's easy to get confused when looking at the numbers. You might accidentally do 8 – 12 instead of 12 – 8.
- Fix: Always check which number is bigger. The team that is ahead has the bigger score.
- Mistake: Forgetting to write down the answer.
- Why it happens: You might be so focused on counting or subtracting that you forget to write the final number.
- Fix: After you subtract, always write down your answer. You can say it out loud too.
- Mistake: Thinking that the difference is the same as the score.
- Why it happens: Some children mix up the idea of "how many points ahead" with "what the score is".
- Fix: Remember that the difference is how much one number is bigger than another, not the actual score itself.
Parent and carer guide
As a parent or carer, you can help your child practice finding score differences by:
- Watching a basketball game together and asking them to find how many points one team is ahead.
- Using a number line to help them count backwards when subtracting.
- Practising with simple subtraction problems at home, like 15 – 8 = ?
- Encouraging them to explain their thinking to you – for example, "How did you know that Team A was ahead by 7 points?"
- Not worrying if they make a mistake – it's part of learning!
You can also use other games or activities to reinforce subtraction, such as:
- Using toys or counters to show how many more one group has than another.
- Playing subtraction games online or in apps.
- Using real-life examples like counting how many more cookies you have than your sibling.

FAQ
How do I know which team is ahead?
The team with the higher score is ahead. You can compare the two numbers and see which one is bigger.
What if the scores are the same?
If both teams have the same score, then neither team is ahead. It's a tie!
Can I use a number line to find the difference?
Yes! You can start at the bigger number and count backwards to the smaller number. The number of steps you take is the difference.
Why do I need to know how many points a team is ahead?
It helps you understand the game better. It's also a useful maths skill that you can use in many other situations, like comparing prices or measuring differences in height.
Can I use subtraction for other sports?
Yes! You can use subtraction for any sport where teams score points. For example, in football, you can find how many points one team is ahead by subtracting the other team’s score.
