Words to know

continuous activity
Moving at a steady, moderate to vigorous pace without stopping, like a steady jog or bike ride.
interval activity
Taking turns between harder bursts and easier recovery, like 30 seconds fast, 30 seconds easy.
work interval
The harder part of an interval workout.
recovery interval
The easier part, where your heart rate and breathing come down a bit.
sustain
To keep something going for a long time.
hydration
Drinking enough water so your body works well.

Remember from Grade 5

In Grade 5 you planned a 20-minute DPA with a warm-up, a moderate to vigorous main part and a cool-down. You checked how hard you were working with the talk test, your heart rate (count for 15 seconds, × 4) and the 0 to 10 effort scale, and you learned about recovery.

This year you'll learn two ways to build the main part, continuous and interval, and how to keep going when it gets hard.

Two ways to keep moving

Think of a long winter walk on a snowshoe trail: steady, steady, steady. Now think of a game of tag: sprint, stop, dodge, jog, sprint again.

Both keep you active for a long time. They are two different patterns of activity.

Continuous and interval activity

  • Continuous activity: You move at a steady moderate to vigorous pace the whole time. Examples: a steady jog, a bike ride, swimming lengths, cross-country skiing, dancing to a long playlist. Effort stays about the same, maybe 5 to 7.
  • Interval activity: You switch between work intervals (harder, effort about 7 to 9) and recovery intervals (easier, effort about 3 to 5). Examples: 30 seconds fast skipping, 30 seconds slow marching, repeated. Many games, like soccer, basketball and tag, are naturally interval activities.

Both can build cardiorespiratory endurance. Continuous activity helps you practise pacing. Intervals let you work harder for short bursts, and many people find them less boring.

Keep the main part going

In DPA, aim to keep moving for the whole main part. "To the best of your ability" means your best today. Some tricks:

  • Start slower than you think. You can speed up later.
  • Use a recovery interval instead of stopping completely. Walk instead of sitting down.
  • Drink water before, during and after, especially on hot days.
  • Dress for the weather: layers in winter, a hat and sunscreen in summer.
  • Check in with the talk test or effort scale every few minutes.

When it gets tough: coping strategies

Around the middle of a hard activity, your mind might say, "I want to stop." That's normal. Here are ways athletes cope with that feeling:

  • Chunking: "Just one more interval." "Just to the next tree."
  • Positive self-talk: "I'm strong. I can do 30 more seconds."
  • Focus on your breathing: a steady rhythm, like in for 3 steps, out for 3.
  • Music or a partner: they make time pass faster.
  • Remember your why: "I want to keep up in soccer."

But know the difference between tough and unsafe. Dizziness, chest pain, feeling sick, or not being able to catch your breath mean stop and tell a grown-up. If you have asthma, follow your asthma plan.

Listen to your body

Effort numbers are personal. If your recovery interval still feels like a 9, make your work interval a little easier. The goal is to keep moving for the whole main part, not to burn out in the first 3 minutes.

Worked example

Let's build an interval DPA

Plan a 20-minute DPA for a backyard, with intervals in the main part.

  1. Warm-up (5 min): march, arm circles, side shuffles, easy jog on the spot, building from effort 2 to 4.
  2. Main part (10 min): 30 seconds work, 30 seconds recovery. Each round is 1 minute, so 10 rounds = 10 minutes. Work moves: fast skipping, high knees, jumping jacks, fast feet, shuttle runs between two shoes 10 metres apart. Recovery: walking or marching.
  3. Cool-down (5 min): 2 minutes walking slower and slower, then static stretches held about 20 seconds.
  4. Check the total: 5 + 10 + 5 = 20 minutes.

A 20-minute DPA: 5-minute warm-up, 10 rounds of 30 seconds work / 30 seconds recovery, 5-minute cool-down.

The interval DPA from the example, drawn to scale: 5 + 10 + 5 = 20 minutes. Each minute of the main part is one work burst and one recovery burst.
Worked example

Let's read heart-rate data

Nadia counted her pulse for 15 seconds at different times: end of warm-up 24, after a work interval 40, after a recovery interval 33, end of cool-down 25. Find each heart rate. What does the pattern show?

  1. Multiply each count by 4: 24 × 4 = 96 bpm; 40 × 4 = 160 bpm; 33 × 4 = 132 bpm; 25 × 4 = 100 bpm.
  2. From work to recovery, her heart rate dropped 160 − 132 = 28 bpm in 30 seconds. Her heart was recovering.
  3. Even in recovery (132 bpm), she was still working at a moderate level, so the main part kept her heart rate up the whole time.
  4. After the cool-down she was back near her warm-up level (100 bpm).

Heart rates: 96, 160, 132, 100 bpm. Her heart rate went up in work, down a bit in recovery, and back down after the cool-down: the interval pattern.

What if...

A game of tag is secretly an interval workout: sprint, dodge, stop, giggle, repeat. Nobody has ever said, "Wait, I need to check my heart rate before I tag you!"

Hands-on activity

Continuous vs. interval test day

You need: a timer, a skipping rope or a clear path, paper and a pencil, and a water bottle.

  1. Day 1: Do a 20-minute DPA with a continuous main part (10 minutes of steady jogging, biking or dancing).
  2. Day 2: Do a 20-minute DPA with an interval main part (10 rounds of 30 seconds work, 30 seconds easy).
  3. Each day, check your heart rate and effort number at the end of the warm-up, the middle of the main part and the end of the cool-down. Record them in a table.
  4. Compare: Which pattern felt harder? Which did you enjoy more? Which coping strategy helped you keep going?

Safety: Run or skip on a flat, clear surface. Wear running shoes. Drink water. Stop if you feel dizzy or sick, or have chest pain.

For parents and teachers

Big idea: Grade 6 students take part in at least 20 minutes of sustained moderate to vigorous activity each school day, with a warm-up and cool-down, and monitor their effort. This lesson compares continuous and interval activity and teaches coping strategies for sustaining effort.

How to help at home:

  • Try both DPA patterns with your child and compare how they feel.
  • Help with timing (a phone timer or interval app works well).
  • Model coping talk: "Just to the next lamp post."

Common difficulties:

  • Starting too fast. Encourage a slow start and a strong finish.
  • Stopping completely in recovery. Walking keeps the activity going.
  • Heart-rate arithmetic. × 4 is double, then double again.

Health note: The numbers are for learning, not medical checks. Stop activity and seek advice for chest pain, fainting, unusual shortness of breath or dizziness. Children with asthma or other conditions should follow their care plan. Offer water and dress for the weather.

Social-emotional learning: Coping when activity gets hard builds stress management and coping (A1.2) and perseverance (A1.3).
