We all like to read books. While reading, we sometimes get lost in the words. To avoid this, we use finger or a pencil to point at the words.
In the same way, we use the computer mouse to point on the screen.
A computer mouse is a pointing device that is used to point at and select things on the computer screen. A mouse is kept on the mouse pad.

Keyboard
We write on paper with pencil. We write words and sentences.
What if we want to write words and sentences on the computer? How can we write on a computer?
A keyboard is a part of the computer that helps us write on it. We use the keys on the keyboard to write what we want.
Writing on the computer using a keyboard is called typing.
But how do we know where we are typing?
We have a blinking line on the screen! This blinking line is called a cursor. The cursor helps us to know where we can type on the screen. A standard keyboard has 104 keys on it. Did You Know?

Voice Typing
Some computers can listen to your voice and type what you say!
This is called voice typing. It works using AI. You say: “My name is Mel.”
The computer types: My name is Mel.
Types of Keys
Let us learn about the different types of keys.
Alphabet Keys
We have 26 letters in the English alphabet. For each letter of the alphabet, we have one key on the keyboard. These keys are called alphabet keys.
Cursor
We can use these keys to type words and sentences on a computer.
Alphabet keys
Think and Tell
Which keys will you use to type your name?
Number Keys
What if we want to type numbers?
We can use the number keys to type numbers on the computer.
Number keys
We have a key for each number: 0, 1, 2, 3, 4, 5, 6, 7, 8, and 9.
We can type any number using these number keys.
Which number keys will you use to type your age?
Look at the keyboard below. Colour the alphabet keys blue and the number keys green. Do It Yourself 5A
Special Keys
There are some special keys on a keyboard. Let us learn about them.
Spacebar: The spacebar key helps us to make a space between two words. Pressing the spacebar once makes the cursor move one place. In this way, a space is created every time the spacebar key is pressed. The spacebar is the largest key on the keyboard.
Spacebar
Enter: The enter key helps us to go to the next line while typing. The cursor goes to the next line when we press the enter key.
Backspace: We could sometimes make mistakes while typing. The backspace key helps us to erase those mistakes. On pressing the backspace key, the letter or the number before the cursor is erased.
Delete: The delete key works like the backspace key. On pressing the delete key, the letter or the number after the cursor is erased.
Delete

AI Activity
Magic Sketchpad
Magic Sketchpad is a website that uses Artificial Intelligence (AI) to help complete your drawings. When you start drawing something, the computer guesses what you are trying to make and adds to it.
Objective: The aim of this activity is to help students understand that AI can learn from drawings and try to guess what we are making.
As students draw, they will see how the computer watches their lines, makes a smart guess, and then helps complete the picture.
1 Open the following website with the help of your teacher: https://magic-sketchpad.glitch.me
2 You will see a blank white area in the centre.
3 A list of object names appears at the top showing “cat,” “car,” “tree,” etc. options.
4 Choose one of the words from the list. For example, select “flower”.
5 Start drawing in the white box using your mouse. Draw the first petal of the flower.
6 Watch what happens! The computer will start to complete your drawing. It is guessing what you are drawing and helping you finish it.
7 If you want to try again, click on the “Clear ” button to erase and start a new drawing.
8 Try drawing other things from the list like a house, sun, or dog!
Have you ever asked a speaker to play a song or talked to a toy that answers back? These are examples of machines using something called AI.
Artificial Intelligence
AI stands for Artificial Intelligence.
It means making machines smart so they can do things like understand your words, follow your instructions, or even learn from what they see or hear.
AI Around Us
• Talking Toys: Some toys use AI to understand your voice and respond with sounds, songs, or even short sentences.
These machines do not think or feel like humans, but they can be trained to do certain tasks.
AI devices are all around us. There are many types of machines that use Artificial Intelligence (AI) to perform tasks or respond to us. Some examples of such AI devices are:
• Smart Speakers: These speakers respond to your voice commands. They use AI to understand your voice commands, like when you ask them to play music or tell you a story.
• Robot Helpers: These machines help us with daily tasks at home. They can clean floors, cook food, etc. They do work in the same way as a human does.
•
Selfie Magic: Some phones use AI to edit your selfies. The AI can adjust lighting, smooth out backgrounds, or add fun filters.
• Learning Games: These are educational games that you play on your computer. Some of them use AI to adjust the difficulty level as you play. For example, AutoDraw!
Fun with AI: Using AutoDraw!
Let us perform the following experiment to understand how AI uses computer vision to see and understand things.
