Hidden Multiplication
Screen-Time Blocks times-table story
A playful story page showing how screen-time blocks can teach multiplication in real life.
Quick answer
Multiplication is hidden all around us, even in screen time! When you watch a 30-minute video, you can think of it as 30 groups of 1 minute, or 30 × 1 = 30. Every time you play a game, watch a show, or scroll through apps, you're using multiplication without even realising it.Learning outcome
By the end of this page, you will understand how screen time can help you learn multiplication by seeing equal groups and repeated addition in everyday activities. Success signs:- You can count how many minutes you spend on a screen in equal groups
- You can see how repeated addition and multiplication are the same thing
- You can make up your own screen-time multiplication story
- You can explain how your screen time shows multiplication
Why this matters
Multiplication is everywhere, not just in maths books. When you play a game, watch a show, or scroll through your phone, you're using maths without even realising it. Understanding how screen time connects to multiplication helps you see that maths is useful, fun, and part of your daily life.How it works
Multiplication is like making equal groups. If you watch 5 episodes of a show and each one is 10 minutes long, you can think of it as 5 groups of 10 minutes. That’s 5 × 10 = 50 minutes total. You can also think of it as adding 10 + 10 + 10 + 10 + 10 = 50 minutes. Both ways give the same answer!Examples you can see
Let’s look at some screen time examples where multiplication hides in plain sight: Example 1: Watching a YouTube video You watch a 15-minute video. If you watch it 3 times, how many minutes did you watch?- 15 + 15 + 15 = 45 minutes
- Or 3 × 15 = 45 minutes
- 20 + 20 + 20 + 20 = 80 minutes
- Or 4 × 20 = 80 minutes
- 12 + 12 + 12 + 12 + 12 = 60 minutes
- Or 5 × 12 = 60 minutes
Try it as a mini adventure
Adventure: Screen-Time Detective You are a detective who needs to solve the mystery of how much time you spend on screens each week. You have a notebook and a timer. 1st time: Write down how many minutes you spend on one screen activity today. 2nd time: Choose another screen activity and write how long it took. 3rd time: Add both times together. 4th time: If you do the same screen activity 3 times, how many minutes have you spent? 5th time: Now, try to write the multiplication sentence for your screen time. 6th time: Can you think of a way to show this with objects or drawings? Example: If you play a game for 15 minutes and watch a video for 20 minutes:- Total time = 15 + 20 = 35 minutes
- If you play the game 2 times, that’s 2 × 15 = 30 minutes
Common mistakes
- Mistake: Thinking that 3 × 10 = 30, but counting wrong.
Why it happens: Confusing multiplication with addition.
Fix: Use your fingers or draw groups to check your answer. - Mistake: Forgetting to add the same number multiple times.
Why it happens: Not understanding that multiplication is repeated addition.
Fix: Write out the addition sentence first to check your multiplication. - Mistake: Counting screen time in minutes only, not thinking of groups.
Why it happens: Not seeing the equal groups in screen time.
Fix: Think of your screen time as groups of the same amount.
Parent and carer guide
You can help your child by:- Asking them to count their screen time in groups
- Encouraging them to write multiplication sentences for their screen time
- Playing the Screen-Time Detective game together
- Using everyday screen time to show how multiplication works
- Not worrying if they make mistakes – it’s part of learning!
- "How many times did you watch that video?"
- "If you watched it 4 times, how many minutes did that take?"
- "Can you show me with your hands how many groups you had?"
- They might get confused at first – that’s normal!
- They may not know all the facts yet – that’s okay too!
- They might count instead of multiply – that’s fine, it’s a good start!

- How many minutes are in 5 groups of 8 minutes?
- 3 × 10 = 30 minutes
- 2 × 15 = 30 minutes
- 3 × 20 = 60 minutes

- 5 × 8 = 40 minutes
FAQ
What is multiplication?
Multiplication is a way of adding the same number over and over. For example, 3 × 4 means 3 groups of 4, or 4 + 4 + 4 = 12.
Why is multiplication useful?
Multiplication helps us count quickly when we have equal groups. It’s useful for sharing, shopping, and even for screen time!
How can I use screen time to learn multiplication?
Every time you watch a video, play a game, or use an app, you can think of it as equal groups. For example, 3 videos that are 10 minutes each = 3 × 10 = 30 minutes.
What if I don’t know my multiplication facts?
That’s okay! You can still use addition to solve multiplication problems. For example, 4 × 5 = 5 + 5 + 5 + 5 = 20.
Can I make up my own screen-time multiplication story?
Yes! You can tell a story about how much time you spend on different screen activities and turn it into a multiplication problem.
