Mini-lesson — Why rest and sleep are important

Your body is busy every day. You walk, run, play, think, and learn. To stay healthy, your body and brain need rest and sleep.

What is rest?

  • Rest is when you give your body a short break.
  • You might sit down, read quietly, draw, or close your eyes for a moment.
  • Rest helps your body feel calm and your mind feel steady.

What is sleep?

  • Sleep is a longer, deeper kind of rest.
  • When you sleep at night, your body is still working on the inside.
  • Your brain sorts new memories and your body grows and repairs.

How do we feel when we do not rest?

  • You may feel very tired or grumpy.
  • It can be harder to listen and concentrate.
  • You might bump into things or make more mistakes.

Bedtime routines

  • A bedtime routine is a set of calm steps you do every night.
  • For example: wash, brush teeth, put on pyjamas, read a story, lights out.
  • Doing the same steps each night tells your body it is time to slow down.

Healthy sleep habits

  • Going to bed at about the same time each night.
  • Keeping the room dark, quiet, and comfortable.
  • Turning off bright screens (TV, tablet, phone) before bed.

When you get good rest and sleep, it is easier to learn, play safely, and feel happy the next day.

Guided Practice — Notice tired signs and plan a calm bedtime

You will learn to notice when your body feels tired and build a calm bedtime routine with an adult.

  1. Talk about tired signs: With an adult, make a list of signs that you are tired, such as yawning, rubbing eyes, moving slowly, feeling grumpy.
  2. Make two faces: Draw a small picture of yourself when you feel rested and when you feel very tired. Talk about the difference.
  3. Choose calm activities: Think of 2–3 quiet things you can do before bed, like reading, looking at pictures, or listening to soft music.
  4. Build a bedtime routine: On small cards, write or draw steps such as: wash, brush teeth, pyjamas, story, lights out. Put them in order with your adult.
  5. Practise the steps: Pretend it is bedtime and act out the routine. Say each step out loud: "Now I brush my teeth."
  6. Use the tracing pad: Choose words like rest, sleep, bed, calm, night or dream and trace them slowly.
  7. Say a sleep sentence: After tracing, say a sentence such as "Sleep helps my brain learn." or "Rest helps my body feel better."

Practice 1 — Sort rest, calm, and busy activities

Decide which activities help your body rest and which ones keep it busy.

  1. On a page, draw two boxes and label them "Rest and calm" and "Very active and busy".
  2. With an adult, think of different activities, such as: reading a book, jumping on a trampoline, watching a calm story, running in the park, colouring quietly, shouting and chasing.
  3. Write or draw each activity on a small card. Place the card in the box that fits best.
  4. Circle or colour the activities that are good to do before bedtime to help you feel calm.
  5. Talk about one change you could make if your evenings feel too busy, such as choosing a calm game instead of a loud one before bed.

Practice 2 — Design your bedtime routine poster

Create a small poster that shows your own bedtime routine in 4–6 clear steps.

  1. At the top of your page, write a title such as "My Bedtime Routine".
  2. Think of the steps you usually do before sleep, for example: wash, brush teeth, pyjamas, story, lights out.
  3. For each step, draw a small picture and write a short label, such as "Brush teeth" or "Read a story".
  4. Put numbers 1, 2, 3, 4, 5 next to the steps to show the order.
  5. Colour your poster and hang it near your bed as a reminder of your calm bedtime routine.

Practice 3 — How does my body feel?

Practise noticing and talking about how your body feels when you are rested or tired.

  1. Draw two simple bodies on a page. Label one "Rested" and one "Tired".
  2. On the rested body, add small notes like "bright eyes", "smiling", "ready to learn".
  3. On the tired body, add notes like "yawning", "rubbing eyes", "hard to listen".
  4. With an adult, practise saying sentences such as "I feel tired. I need a rest." or "I slept well. I feel ready to learn.".
  5. At the bottom of the page, write one promise to yourself, such as "I will try to go to bed on time."
