Key Point: Start sequence: Power On -> Booting (loading) -> Welcome/Home Screen -> Ready to Use
What it means: "Start" (or switch on) is when we turn a computer on so it becomes ready to use. "Shut Down" (or switch off) is when we close everything and turn the computer off safely.
Why it is important: Starting correctly lets the computer get ready and load its programs. Shutting down properly keeps your work safe and protects the computer from damage.
Key Point: Power button → ON (press) → Computer starts
What this topic means: "Parts Related to Starting and Shutting" teaches young learners the parts of a computer they press or use when they turn it on (start) and turn it off (shut down), and the simple safe steps to follow.
Main parts:
Simple steps to Start:
Simple steps to Shut Down (safe way):
Safety tips: Never unplug while the computer is working; always save your work before shutting down; keep liquids away from parts.
Key Point: ON = 1 (line symbol) • OFF = 0 (circle symbol)
The power button is the small button on electronic things (like a TV, computer, toy or phone) that turns them ON or OFF. When you press the power button the device starts (turns ON). When you press it again or press and hold it for a few seconds, the device goes OFF or shuts down.
We see special pictures (symbols) on and near the power button so everyone can recognise it easily. The most common power symbol looks like a circle with a line touching it. The circle stands for OFF (like the number 0) and the line stands for ON (like the number 1). Put together they mean this button controls power.
Where to find it: The power symbol is often on the front of a TV, on the top of a toy, near the keyboard of a laptop, or on the side of a phone. Some devices have a small light near the button that shows if the device is ON (light is on) or OFF (light is off).
Safety and help: A Class 1 child should ask an adult before using buttons on big devices. If a device does not turn off, ask an adult to help.
Key Point: Boot sequence (conceptual): Power On → POST (Power-On Self Test) → Bootloader → Operating System loaded
Starting a computer means turning it on so you can use programs, games, or learn. Follow these simple steps to start a desktop or a laptop safely and correctly.
Safety tips: Keep liquids away from the computer, do not touch inside the CPU, and always shut down properly when you finish (use the operating system's Shut Down option).
Key Point: Shut down = Save work + Close apps + Start/Apple menu → Power → Shut down + Wait
Shutting down a computer means turning it off in a safe way so your work is saved and the computer can stop running. Follow these easy steps:
Simple safety tips: do not unplug or switch off the power while the computer is shutting down, because that can make you lose work or damage files. If you are unsure, ask an adult or teacher for help.
Note for laptops: you can also close the lid after shutdown; closing the lid while the computer is still shutting down can interrupt the process. Some devices have a “sleep” mode — shutting down is different because sleep keeps the computer on in low power, while shut down turns it completely off.
Key Point: Restart = Close programs + Reboot (power cycle)
Computers have three ways to stop working for a while: Restart, Sleep and Hibernate. Each one helps the computer and the user in a different way.
Simple safety tips: always save important files before restarting or hibernating; use Sleep for short breaks and Hibernate for longer breaks or low battery.
Key Point: Access = Identity (username) + Secret (password) [+ MFA (optional)]
Logging in means telling a computer or device who you are so it can give you the right files and programs. You usually enter a username and a password (and sometimes a code sent to your phone). When you log in, the computer checks your details and opens a personal session for you.
Logging out means ending that personal session so the next person cannot use your account. Logging out closes access to your files and programs and returns the computer to a state where someone else can log in safely.
Locking (screen lock) is a quick way to stop anyone from using your account while you are away, but it does not close your programs. The session stays open and your work remains where you left it. To get back in, you usually type your password again.

Classroom activities and exercises for the topic Start and Shut Down help Class 1 children learn how to switch a computer on and off safely and in the correct order. These activities are hands-on, simple, and repetitive so young learners remember the steps. The teacher demonstrates first, then children practise with a real computer, a switched-off classroom PC, or a toy/mock computer.
Short, repeated practice with praise and picture cues helps children remember. Use bright, simple images showing each step and encourage children to sequence picture cards in the right order.
