ScratchJr page timers maths mission

A practical mini-mission using page timers to practise time language through questions, examples and child-friendly challenges.

Quick answer

You can use page timers in ScratchJr to learn how to tell time, practice counting, and measure how long activities take.

Learning outcome

By the end of this page, you will be able to use page timers in ScratchJr to measure time and understand how long different activities take, and you will know how to use time words like "seconds", "minutes", and "longer" or "shorter". Success signs:
  • You can start and stop a timer in ScratchJr
  • You can say how long an activity took using seconds or minutes
  • You can compare how long different tasks take
  • You can plan a simple activity using a timer

Why this matters

Using page timers in ScratchJr helps you learn about time in a fun way. It's like having a special stopwatch that you can use in your own digital world. You'll learn how to measure how long things take, which helps in real life too – like knowing how long it takes to brush your teeth, eat lunch, or play a game. This is useful for planning your day, being on time, and understanding how fast or slow things happen.

How it works

In ScratchJr, a page timer is a special tool that counts up or down. You can set it to show how long something takes. Here’s how to use it:
  1. First, open ScratchJr and find the timer tool.
  2. Click on the timer to start it.
  3. When the activity is done, click the timer again to stop it.
  4. Look at the numbers to see how long it took.
You can also use the timer to help you plan. For example, if you want to play a game for 5 minutes, you can set the timer to count down from 5 minutes and stop when the game is over.

Examples you can see

Imagine you are playing a game in ScratchJr where you need to build a tower with blocks. You want to know how long it takes you to build it. You can:
  1. Start the timer when you begin building
  2. Stop the timer when you finish
  3. See how many seconds or minutes it took
Example: If you start building at 10:00 and finish at 10:03, your tower took 3 minutes to build. Another example: In a race game, you might use the timer to see who finishes first. You can compare how long it took each character to finish the race. Timer Examples in ScratchJr
Activity Time Taken Time Words
Building a house 2 minutes Longer than usual
Running to the finish line 45 seconds Quick
Counting to 20 1 minute Slow

Try it as a mini adventure

Adventure: The Timer Challenge You are a time detective in a magical world where everything moves fast or slow. Your mission is to use page timers to solve puzzles and find out how long different events take.
  1. First, you need to set the timer for 10 seconds.
  2. Then, you do a fun activity like jumping up and down.
  3. When you're done, stop the timer and see how long it took.
  4. Next, try the same activity but for 30 seconds.
  5. Compare how long each one took and decide which was longer or shorter.
This adventure helps you understand how time works in a fun way. You can do this with your family or by yourself.

Common mistakes

  • Mistake: Forgetting to stop the timer. Why it happens: It's easy to get distracted while playing. Fix: Always remember to click the timer again when your activity is done.
  • Mistake: Not knowing how to read the timer numbers. Why it happens: The timer might count in seconds or minutes, which can be confusing. Fix: Practice starting and stopping the timer to see how the numbers change.
  • Mistake: Comparing times incorrectly. Why it happens: Sometimes 30 seconds feels longer than 1 minute. Fix: Use a real clock or watch to help compare how long different times feel.

Parent and carer guide

As a parent or carer, you can help your child learn about time using ScratchJr timers by:
  • Playing the timer game together and asking questions like, "How long did that take?"
  • Using real-life timers at home to compare how long things take, such as cooking or cleaning.
  • Encouraging your child to plan a short activity using the timer, like reading a story for 5 minutes.
  • Checking that the timer is working correctly by starting and stopping it yourself.
  • Using the timer to make learning fun and interactive.
What to say:
  • "Let's see how long it takes to jump 10 times."
  • "Did you know that 60 seconds is the same as 1 minute?"
  • "How does your timer compare to the one on the wall?"
What not to worry about:
  • It's okay if your child doesn't get the exact time at first.
  • They are learning about time and how to use tools to measure it.
  • Focus on the fun of timing activities, not perfect accuracy.

Practice questions

  1. How many seconds are in 1 minute?
  2. If you play a game for 2 minutes, how many seconds is that?
  3. Which is longer: 30 seconds or 1 minute?
  4. If a timer starts at 0 and stops at 45, how long did the activity take?
  5. How long would it take to count to 20 if you count one number every 2 seconds?
Answers:
  1. 60 seconds
  2. 120 seconds
  3. 1 minute is longer
  4. 45 seconds
  5. 40 seconds (20 numbers × 2 seconds each)
