Scratch timer games maths mission

A practical mini-mission using timer games to practise time through questions, examples and child-friendly challenges.

Quick answer

Scratch timer games help you learn about time by setting and measuring how long tasks take, which helps you understand how long 1 minute, 5 minutes, or 10 minutes really feels.

Learning outcome

By the end of this page, you will be able to use a timer to measure how long it takes to do different tasks, and you will understand how time works in seconds and minutes. Success signs:
  • You can set a timer for 10 seconds and stop it when it finishes
  • You can tell how many seconds are in 1 minute
  • You can compare how long different activities take
  • You can use a timer to plan your day or play a game

Why this matters

Time is everywhere! When you play a game, eat lunch, or do your homework, you are using time. Learning how to measure time helps you understand how long things take. In Scratch, you can make your own timer games to practice this. This helps you get better at planning, managing time, and even playing games with friends.

How it works

In Scratch, you can make a timer game that counts down from a set number of seconds or minutes. You can make the timer:
  • Count down from 30 seconds
  • Count up from 0 seconds
  • Stop when it reaches 1 minute
The timer helps you learn how much time is passing. You can use it to:
  • Time how long it takes to do a puzzle
  • See how fast you can run
  • Measure how long you spend on your homework

Examples you can see

Let’s imagine you are making a timer game in Scratch. Here are some examples of how you can use it: Example 1: Timer for 10 seconds
  • You start the timer
  • It counts down from 10 to 0
  • When it reaches 0, it says “Time’s up!”
Example 2: Timer for 30 seconds
  • You start the timer
  • It counts down from 30 to 0
  • When it reaches 0, it plays a sound
Example 3: Timer for 1 minute
  • You start the timer
  • It counts down from 60 seconds to 0
  • When it finishes, it shows a message

Try it as a mini adventure

Adventure: The Timer Challenge You are a space explorer on a mission to collect stars. You have a special timer that can help you. You must complete 3 tasks:
  1. Collect 5 stars in 1 minute
  2. Jump 10 times in 30 seconds
  3. Draw a picture in 20 seconds
You will use your Scratch timer to see how much time you have left for each task. Try to do each task as quickly as you can, but don’t rush so much that you make mistakes!

Common mistakes

  • Mistake: Thinking 1 minute = 10 seconds
    Why it happens: Not knowing how many seconds are in a minute
    Fix: Remember that 1 minute = 60 seconds
  • Mistake: Setting the timer to 10 seconds but it counts to 0 in 60 seconds
    Why it happens: Confusing seconds with minutes
    Fix: Check if you are using seconds or minutes in your timer
  • Mistake: Forgetting to start the timer
    Why it happens: Not clicking the green flag
    Fix: Click the green flag to start your timer

Parent and carer guide

Parents and carers can help by:
  • Encouraging children to try different timer lengths (10 seconds, 30 seconds, 1 minute)
  • Using the timer to make fun challenges at home
  • Practising how long it takes to do daily tasks like brushing teeth or tying shoes
  • Helping children understand how time works in real life
  • Not pressuring children to be fast, but to enjoy the learning
What to say:
  • “Let’s try timing how long it takes to get dressed.”
  • “Can you do 5 jumping jacks in 10 seconds?”
  • “How many seconds do you think it takes to eat a sandwich?”
What not to worry about:
  • Children may not get the exact time right away
  • It’s okay to make mistakes – they help you learn
  • Focus on the fun and learning, not the speed
