Keyboard And Mouse

What is a Keyboard?
A keyboard is an input device that looks like a typewriter. It has many keys that we press to type letters, numbers and give commands to the computer.

Main parts of a keyboard

• Alphabet keys: A to Z for typing words.
• Number keys: 0 to 9 for typing numbers.
• Space Bar: puts a space between words.
• Enter Key: moves the cursor to the next line or gives a command.
• Backspace: removes the letter before the cursor.
• Shift and Caps Lock: used to type capital letters.
• Arrow Keys: move the cursor up, down, left or right.

How to use a keyboard
Press the key gently. Use Shift plus a letter for a single capital letter; use Caps Lock to type many capital letters. Use Backspace to delete mistakes.

What is a Mouse?
A mouse is a pointing device that helps us move a pointer (cursor) on the screen. It usually has two buttons and a scroll wheel.

Main parts of a mouse

• Left Button: select and open items (single or double click).
• Right Button: opens a small menu with options.
• Scroll Wheel: moves the page up or down.

How to use a mouse
Place your hand on the mouse, move it on the table to move the pointer. Click the left button once to select, click twice quickly (double-click) to open, and hold the left button and move the mouse to drag-and-drop.

Types and care

• Keyboards: wired or wireless.
• Mice: optical (uses light), wireless, or trackball types.
• Care tips: keep them clean, avoid eating over them, don't pull wires, use a mouse pad for smooth movement.

Why they are important
Keyboard and mouse are basic tools to type, play educational games, draw, open files and move around the computer. They help us tell the computer what we want it to do.

A keyboard is an input device that looks like a board full of keys. We press keys to type letters, numbers and to give commands to the computer. A keyboard helps us write stories, search for information, play games and control many programs.

Parts of a keyboard:

• Alphabet keys: A to Z used for typing words.
• Number keys: 0 to 9 above the letters and on the numeric keypad (on some keyboards).
• Spacebar: makes a space between words.
• Enter (Return): moves to the next line or confirms a command.
• Backspace: deletes the character before the cursor.
• Shift: used with a letter to make a capital letter and with number/symbol keys to type the top symbol (for example Shift + 1 = !).
• Arrow keys: move the cursor up, down, left or right.
• Function keys (F1–F12): do special jobs in some programs (for example F1 often opens Help).
• Special keys: Ctrl, Alt, Esc — used with other keys to perform shortcuts.

How it works (simple): when you press a key, the keyboard sends a signal to the computer. The computer reads that signal and shows the matching letter, number or action on the screen.

Care and good habits: keep the keyboard clean, do not spill water, press keys gently, and use correct finger placement to type comfortably.

On a computer keyboard each key has a job. The keys are grouped into categories so we can find and use them easily. Here are the main categories of keys with simple explanations:

• Alphanumeric keys: Letters A–Z and numbers 0–9. These are used for typing words and numbers (like writing your name or a message).
• Modifier keys: Keys such as Shift, Ctrl (Control) and Alt. They change the action of other keys. For example, holding Shift makes a letter capital (a → A).
• Function keys: Labeled F1 to F12 at the top. Each can do special jobs depending on the program (for example, F1 often opens Help).
• Navigation keys: Arrow keys, Home, End, Page Up, Page Down. They help move the cursor around without using the mouse.
• Control keys: Keys like Enter, Backspace, Tab, and Escape (Esc). They let you start a new line (Enter), delete a character (Backspace) or move to the next field (Tab).
• Special keys: Spacebar (adds a space), Caps Lock (types letters in all capitals when on), and Print Screen (takes a picture of the screen).
• Numeric keypad: A block of number keys on the right (on many keyboards). It helps to enter numbers quickly, like on a calculator.

Knowing these categories helps children find keys faster and learn simple shortcuts that make typing and working on the computer easier.

What is a keyboard? A keyboard is an input device used to type letters, numbers and to give commands to the computer. It has many keys: alphabet keys, number keys, special keys (Enter, Spacebar, Backspace), modifier keys (Shift, Ctrl, Alt), and arrow keys.

Basic keyboard skills every Class 3 student should learn

• Correct posture: Sit straight, feet on the floor, elbows near the body. Keep the keyboard at a comfortable height so wrists are relaxed.
• Hand and finger placement (home row): Place left-hand fingers on A, S, D, F and right-hand fingers on J, K, L, ; (semicolon). Thumbs rest on the Spacebar. This is called the home row.
• Using fingers correctly: Use each finger for keys closest to it. Return fingers to the home row after pressing keys.
• Typing simple keys: Learn keys like Spacebar (gives a space), Enter (moves to next line), Backspace (deletes the character to the left), and Delete (removes the character to the right).
• Capital letters: Use the Shift key with the letter to make a capital letter, or use Caps Lock to type many capital letters continuously.
• Arrow keys: Use these to move the cursor up, down, left and right without using the mouse.
• Shortcuts: Simple shortcuts make work faster (for example, Ctrl + C to copy and Ctrl + V to paste). These are taught gradually.

How to practice (step-by-step)

1. Start by learning where the letters are. Find A, S, D, F and J, K, L, ; without looking.
2. Practice typing your name and short words using the correct fingers.
3. Type short sentences: slowly at first, then a little faster as you get comfortable.
4. Try simple tasks like deleting a mistake with Backspace, moving to the next line with Enter, or making a capital letter with Shift.
5. Play typing games or timed exercises to build speed and accuracy.

Safety and care

• Do not eat or drink near the keyboard to avoid spills.
• Keep the keyboard clean by wiping it gently with a dry or slightly damp cloth (with adult supervision).
• Take short breaks during long practice to rest your fingers and eyes.

Why these skills matter

Basic keyboard skills help students write stories, do schoolwork, and use educational games more easily. Good habits now make typing faster and more comfortable later.

What is a mouse?

A mouse is a small hand-held device used with a computer to move the pointer (cursor) on the screen. When you move the mouse on a flat surface, the pointer moves in the same direction on the computer screen. You use the mouse to click icons, open files, play games and draw pictures.

Main parts of a mouse

• Left button — used to select and open things.
• Right button — used to open a small menu with more choices.
• Scroll wheel — used to move the page up and down.
• Body/cover — where you place your hand.
• Connector (USB or wireless receiver / built‑in Bluetooth) — connects the mouse to the computer.

How to use a mouse (easy steps)

• Place the mouse on a flat surface and rest your hand on it.
• Move the mouse to move the pointer on the screen.
• Single‑click (left button) to select an item.
• Double‑click (two quick left clicks) to open a file or program.
• Right‑click to see a menu with actions like copy, paste or delete.
• Click and drag (hold left button while moving) to move objects or draw shapes.
• Use the scroll wheel to move up and down a page.

Types of mouse

• Wired mouse — connects to the computer with a cable (USB).
• Wireless mouse — uses batteries and connects by Bluetooth or a tiny receiver.
• Optical/laser mouse — uses light to detect movement (most modern mice).
• Older mechanical mouse — had a rolling ball inside (less common now).

Care and safety

• Keep the mouse clean and dry. Wipe the bottom if the pointer jumps.
• Don’t pull the cable roughly and replace batteries when needed.
• Use a mouse pad or smooth surface for best performance.

A mouse is a pointing device used with a computer. It helps you move the pointer (cursor) on the screen and tell the computer what to do. There are several common mouse actions that every Class 3 student should know:

• Move: Slide the mouse on the table to move the pointer on the screen.
• Left-click: Press and release the left button once to select an item (for example, select an icon).
• Right-click: Press and release the right button once to open a small menu with more choices (context menu).
• Double-click: Quickly press the left button twice to open files or folders.
• Drag and drop: Hold down the left button while moving the mouse to pick up and move an item, then release the button to drop it in a new place.
• Scroll (mouse wheel): Roll the wheel between the buttons to move up and down a page.

These actions let you open programs, move pictures, play games, and work with pictures and text. Practice each action slowly at first until you are comfortable. Always keep your hand relaxed and the mouse on a flat surface for smooth movement.

The keyboard and the mouse are two important tools we use to tell the computer what to do. The keyboard is used to type letters, numbers and shortcut keys. The mouse is used to point, click and drag things on the screen. When we use them together, we can do many tasks quickly and easily.

How they work together:

• Select and edit text: Use the mouse to click and drag over text to select it, then use the keyboard to press Delete or Backspace, or press keys like Ctrl+C (copy) and Ctrl+V (paste).

• Open and enter information: Click a text box with the mouse to place the caret (cursor), then type your name or answers using the keyboard.

• Shortcuts and menus: Right-click with the mouse to open a menu, then press an underlined key or arrow keys and Enter to choose an option faster.

• Drawing and editing pictures: Use the mouse to draw or move objects and use keyboard keys (for example, Ctrl+Z to undo) to change your work quickly.

• Games and learning apps: Many games use the keyboard for movement (arrow keys or WASD) and the mouse to aim, click or select items.

Simple tips for using both together:

• Keep your hand on the keyboard for typing and move it to shortcuts when needed.
• Use the mouse to point and select; use the keyboard to type and use shortcut keys to save time.
• Practice common shortcuts: Ctrl+C (copy), Ctrl+V (paste), Ctrl+X (cut), Ctrl+Z (undo), Tab (move to next box).

Using keyboard and mouse together helps you work faster and makes many computer tasks easy and fun.

What it means: Care, safety and good habits are simple rules we follow when using a keyboard and mouse so they last longer and we stay healthy. These rules help keep the computer clean and prevent injuries like sore eyes, wrists or back pain.

Why it is important:

• Keeps the keyboard and mouse working well for a long time.
• Prevents germs and spills that can damage the computer.
• Keeps you comfortable and healthy when using the computer.

Good habits for the keyboard:

• Wash or clean your hands before using the keyboard so keys stay clean.
• Press keys gently — don’t bang them.
• Don’t eat or drink near the keyboard to avoid spills.
• Use a dust cover or keep the keyboard in a clean place when not in use.
• If a key is stuck, ask an adult to help clean it (use a soft cloth or compressed air).

Good habits for the mouse:

• Use a mouse pad so the mouse moves smoothly and the sensor stays clean.
• Keep the mouse on a flat surface and don’t drop it.
• Don’t pull the mouse by its cord; unplug gently if needed.
• Clean the outside with a soft cloth; ask an adult to clean the inside or sensor if needed.

Safety and health tips:

• Sit properly: back straight, feet flat on the floor, and elbows near 90 degrees while typing.
• Keep the screen at least an arm’s length away (about 40–60 cm) and slightly below eye level.
• Follow the 20-20-20 rule to protect your eyes: every 20 minutes look at something 20 feet away for 20 seconds.
• Take short breaks: stand up, stretch hands and fingers, and blink often to keep eyes moist.
• If anything is broken or wet, switch off the computer and tell an adult immediately.

Cleaning steps (with adult help):

1. Turn off and unplug the computer.
2. Use a soft, dry cloth to wipe the keys, mouse and desk.
3. For dirt between keys, use compressed air or a small soft brush.
4. If needed, slightly dampen a cloth with water or mild soap (not alcohol) and wipe; don’t let liquid drip into the keyboard or mouse.

Summary: Be gentle, keep things clean, sit properly, take breaks, and always ask an adult for help with any repairs or deep cleaning. These simple habits keep both you and the computer safe and happy.

Purpose: Practice activities help Class 3 students become confident using the keyboard and mouse. Exercises are short, fun and repeatable so learners improve speed, accuracy and confidence.

Keyboard activities:

1. Finger position and home keys: Teach where to place fingers (left hand on a, s, d, f; right hand on j, k, l, ;). Practice pressing single letters and then short words.
2. Letter and number drills: Type a list of letters (a–z) and numbers (0–9). Move to simple words (cat, sun, bag) and then short sentences (I like my school.).
3. Special keys practice: Show how to use Space, Enter, Backspace, and Shift (for capital letters). Give tasks like type your name, press Enter, then type your age.

Mouse activities:

1. Pointing and clicking: Move the pointer to objects on the screen and left-click to select. Use simple games to click balloons or match pictures.
2. Double-click and right-click: Practice opening a folder with double-click and opening a pop-up menu with right-click (teacher supervision).
3. Drag-and-drop: Drag shapes into boxes or arrange puzzle pieces. Practice dragging with steady movement and dropping in the target area.
4. Scrolling: Use a mouse wheel or scroll bar to move through a long picture or list.

Combined activities and small exercises:

• Open a drawing program, draw shapes with the mouse, and type the shape names below using the keyboard.
• Type a 3–4 line story about your pet, then save the file (teach clicking File > Save).
• Play a timed matching game: match pictures by clicking and dragging; record time and number of mistakes.

Assessment and practice routine: Keep sessions short (10–15 minutes). Track two simple measures: speed (how many words or clicks per minute) and accuracy (mistakes made). Encourage daily practice and show progress charts.

Safety and posture: Sit straight, feet on the floor, elbows near the body, wrists relaxed. Take short breaks to avoid fatigue.

Why this matters (real-life link): Typing helps with homework and writing emails; mouse skills are needed for drawing, games and using tablet/PC apps.
