Maths hiding in screen time: daily limits

Read timers and plan balanced activities.

Quick answer

Maths hiding in screen time: daily limits means using time, counting, and planning to make sure you spend the right amount of time on screens each day – not too much, not too little.

Learning outcome

By the end of this page, you will be able to:
  • Read a timer to track how long you spend on screens
  • Plan your screen time so it fits into your daily routine
  • Use addition and subtraction to check if you’ve stayed within your daily limits
  • Make choices about screen time that help you balance your day

Why this matters

Maths helps you understand how much time you spend on screens and how to plan your day so you have time for everything you enjoy – like playing, reading, eating, sleeping, and learning. When you know how to manage time, you can make better choices and feel more in control.

How it works

Let’s break it down into simple steps:
  1. First, decide how much screen time you can have each day – maybe 1 hour or 2 hours.
  2. Use a timer to track how long you’ve been on the screen.
  3. Count how many minutes or hours you’ve used.
  4. Check if you’ve stayed within your limit by adding or subtracting.
  5. Plan what you’ll do next – maybe take a break, go outside, or do a puzzle.

Examples you can see

Let’s imagine you have a 1-hour screen time limit each day. You start at 3:00 PM and use your timer.
  • At 3:15 PM, you’ve used 15 minutes.
  • At 3:45 PM, you’ve used 45 minutes.
  • At 4:00 PM, you’ve used your full hour and should stop.
You can also use a number line to show how much time you’ve used:
TimeMinutes used
3:00 PM0
3:15 PM15
3:30 PM30
3:45 PM45
4:00 PM60

Try it as a mini adventure

Adventure: Screen Time Tracker You are a time detective and your mission is to track how long you spend on screens each day. Here’s how to start:
  1. Choose a day to track your screen time.
  2. Set a timer for your screen time limit (like 1 hour).
  3. Every 15 minutes, write down how much time you’ve used.
  4. At the end of the day, add up all your screen time.
  5. Compare it to your daily limit and see if you stayed within it.
If you go over, think of a way to balance your day next time – maybe you could play outside for 30 minutes instead.

Common mistakes

  • Mistake: Not checking the timer regularly.
    Why: You might not notice that you’ve used more time than planned.
    Fix: Check the timer every 15 minutes or so.
  • Mistake: Adding up the time wrong.
    Why: You might confuse 30 minutes with 60 minutes.
    Fix: Use a number line or draw a chart to help you add up.
  • Mistake: Thinking you can’t do anything else if you’ve used your screen time.
    Why: You might feel stuck or bored.
    Fix: Plan other fun things you can do when screen time is over – like drawing, reading, or playing with toys.

Parent and carer guide

Parents and carers can help by:
  • Setting up a simple timer or using a phone app to track screen time.
  • Discussing how much screen time is okay with the child.
  • Using the timer together to make it fun and interactive.
  • Helping the child add up the minutes or hours they’ve used.
  • Encouraging the child to plan what they’ll do after screen time.
This is a great way to teach time, addition, and planning. Don’t worry if the child gets it wrong – it’s all part of learning!
