Maths in rowing: match or routine time

Quick answer

You can use maths to read clocks, understand time periods, and know when a rowing routine or match ends.

Learning outcome

By the end of this page, you will be able to read a clock to find out when a rowing routine or match starts and ends, and understand how long it lasts.

• I can tell the time on an analogue clock to the nearest minute.
• I can count how many minutes or hours a rowing routine or match takes.
• I can work out when a routine or match finishes if I know when it starts.
• I can use a timetable to plan when to start and finish rowing activities.

Why this matters

Rowing is a sport where timing is very important. Coaches need to know exactly when a routine starts and ends. You need to know the time so you can be ready for practice, and to understand how long you have to do your best. Maths helps you read clocks, plan your time, and be on time for everything. This skill is useful not just in rowing, but in school, sports, and daily life!

How it works

Let’s learn how to use time in rowing step by step:

1. First, you need to know how to read a clock. A clock has two hands: the short hand shows the hour, and the long hand shows the minutes.
2. Next, you learn how to count time. For example, if a routine starts at 10:00 and lasts for 30 minutes, you can count forward to find out when it ends.
3. Then, you can plan your time. If you know the start and end times, you can work out how long the routine is.
4. Finally, you can use this knowledge to follow a schedule or plan your rowing training.

Examples you can see

Let’s imagine you are at a rowing training session. Here are some examples:

Try to work out these examples:

• Start time: 8:45, Duration: 30 minutes → End time: 9:15
• Start time: 13:00, Duration: 1 hour 15 minutes → End time: 14:15

Try it as a mini adventure

Imagine you are a rower in a school team. You have a rowing routine that starts at 9:00 and lasts for 1 hour and 30 minutes. Your coach says you must be ready 10 minutes before the start.

What time should you arrive?

Step 1: The routine starts at 9:00.

Step 2: You need to be ready 10 minutes before, so you should arrive at 8:50.

Step 3: The routine lasts 1 hour and 30 minutes.

Step 4: So it ends at 10:30.

Now, you want to plan a snack break. You have 15 minutes to eat and rest after the first 45 minutes of your routine. What time does your snack break start?

Step 1: Routine starts at 9:00.

Step 2: First 45 minutes = 9:45.

Step 3: Snack break starts at 9:45.

Step 4: It lasts 15 minutes, so it ends at 10:00.

Common mistakes

• Mistake: Thinking the minute hand shows the hour.
  Why it happens: Confusing the two hands on a clock.
  Fix: Remember: the short hand is the hour hand, the long hand is the minute hand.
• Mistake: Adding time incorrectly.
  Why it happens: Not knowing that 60 minutes = 1 hour.
  Fix: Count in groups of 60 minutes to convert to hours.
• Mistake: Forgetting to add the minutes when the time goes past 12:00.
  Why it happens: Not understanding 24-hour time.
  Fix: Use a 12-hour clock and remember that 12:00 is noon and 00:00 is midnight.

Parent and carer guide

Helping your child understand rowing time maths is easy and fun!

1. Practice reading the clock: Ask your child to tell you the time every morning when getting ready for school.
2. Plan a rowing routine: Create a pretend routine with start and end times, and let your child work out how long it lasts.
3. Use real-life examples: Talk about how long it takes to get to school, or how long a football match lasts.
4. Count backwards: If a routine ends at 10:30 and lasts 1 hour, ask when it started.
5. Keep it light: Don’t make it feel like a test. Make it part of play and daily life.

FAQ

How do I read a clock?
To read a clock, look at the short hand for the hour and the long hand for the minutes. For example, if the short hand is at 3 and the long hand is at 12, the time is 3:00.

Why is timing important in rowing?
Timing is important because rowers need to work together in a team. If one person starts or stops at the wrong time, it can affect the whole crew. Good timing helps them row smoothly and fast.

Can I use maths to plan my rowing training?
Yes! You can use maths to work out when to start and finish, how long each part of training lasts, and when to take breaks. This helps you do your best.

What is the difference between 12-hour and 24-hour time?
12-hour time uses a.m. and p.m. to show morning and afternoon times. 24-hour time counts from 00:00 (midnight) to 23:59 (one minute before midnight).

How can I practice telling time?
You can practice by looking at clocks every day, using a timer, or playing games where you guess the time. Try setting a timer for 10 minutes and see if you can tell when it ends!
