Mario Kart split times maths mission

A practical mini-mission using split times to practise subtraction through questions, examples and child-friendly challenges.

Quick answer

Split times in Mario Kart help you work out how long each part of your race took by subtracting the start time from the finish time.

Learning outcome

By the end of this page, you will be able to use subtraction to find the time it takes to complete each section of a race, like in Mario Kart. Success signs:
  • You can subtract two times to find the difference
  • You can use split times to work out how fast you're going
  • You can solve real-life problems with time subtraction
  • You can play a mini Mario Kart race and track your own split times

Why this matters

Understanding split times helps you measure how fast you're going and compare your performance. In Mario Kart, you can see how much time you gain or lose in each section of the race. This is useful in real life too, like when timing a swimming race, measuring how long it takes to walk to school, or even when cooking to see how long each step takes.

How it works

Split times are used to measure how long each part of a race takes. To find the time for one section:
  1. Look at the time when you start that section
  2. Look at the time when you finish that section
  3. Subtract the start time from the finish time
For example, if you start a section at 1 minute 15 seconds and finish at 1 minute 45 seconds, you subtract: 1 minute 45 seconds - 1 minute 15 seconds = 30 seconds

Examples you can see

Let’s imagine you're racing in Mario Kart and your race looks like this:
Section Start Time Finish Time Time Taken
Starting Line 0:00 0:12 12 seconds
First Turn 0:12 0:25 13 seconds
Speed Boost 0:25 0:38 13 seconds
Final Lap 0:38 1:02 24 seconds
In this example, the final lap took the longest (24 seconds), while the first turn took the shortest (13 seconds).

Try it as a mini adventure

Mario Kart Race Challenge You are racing in a Mario Kart tournament! Your job is to record and calculate the time for each part of your race. Here's your race:
  1. Start: 0:00
  2. First turn: 0:10
  3. Boost section: 0:23
  4. Final stretch: 0:45
  5. Finish: 1:00
Your task is to work out how long each section took:
  1. Starting line to first turn: ? seconds
  2. First turn to boost section: ? seconds
  3. Boost section to final stretch: ? seconds
  4. Final stretch to finish: ? seconds
Hint: Subtract the start time from the finish time for each section.

Common mistakes

  • Mistake: Forgetting to borrow when subtracting minutes and seconds.
    Why it happens: Children might not understand that 1 minute = 60 seconds.
    Fix: When subtracting, if seconds are smaller, borrow 1 minute (60 seconds) from the minutes.
  • Mistake: Adding instead of subtracting.
    Why it happens: Confusing the operation needed.
    Fix: Remember, split times are the difference between two times, so always subtract.
  • Mistake: Not writing times in the same format.
    Why it happens: Mixing up minutes and seconds.
    Fix: Always write times as minutes:seconds, like 1:20.

Parent and carer guide

As a parent or carer, you can help by:
  • Setting up a simple race with your child using a timer
  • Practising subtraction with minutes and seconds using a clock
  • Encouraging your child to write out each time and calculate the difference
  • Using real-life examples like how long it takes to walk to school or cook a meal
  • Checking that they understand the concept of time difference
5-minute activity: 1. Use a stopwatch or timer to time 3 short activities. 2. Write down the start and end times. 3. Subtract to find how long each activity took. 4. Discuss which was fastest or slowest. 5. Repeat with different activities.

FAQ

What is a split time?

A split time is the time it takes to complete one section of a race or activity. It helps you see how fast you're going in each part.

Why do we subtract to find split times?

We subtract because we want to know the difference between when we start and when we finish each section.

How can I practice split times at home?

You can time yourself doing different tasks like jumping, running, or doing chores, then subtract to find how long each one took.

What if I have trouble with minutes and seconds?

Remember that 1 minute = 60 seconds. If you're subtracting and need to borrow, take 1 minute and make it 60 seconds.

Can split times help me in real life?

Yes! Split times are used in swimming, running, racing, and even cooking. They help you measure and improve your performance.
