Preface
Standing at the forefront of the digital and AI revolution, the importance of coding and computational skills has reached unprecedented heights. In today’s professional landscape, whether it is in the fields of medicine, space exploration, education, science, or business, no sector remains untouched by this transformative wave. To thrive in the 21st century, basic computer literacy is no longer sufficient. Learners must evolve into ‘digital natives’ who can fluently read, write, and communicate in the languages that machines and AI comprehend.
Recognising this imperative, the National Education Policy (NEP) 2020 has strongly recommended the integration of coding skills, computational thinking, critical analysis, and problem-solving abilities into the curriculum. Moreover, forward-looking subjects like AI, Data Science, Computer Applications, and IT have been introduced as elective subjects from grade 9 onwards. It wouldn’t be surprising if further transformative measures are taken even at the elementary education level.
Uolo has introduced an innovative 360-degree program for a coding-focused computer science curriculum, known as Tekie, spanning grades 1 to 8. Tekie is a significant stride towards STEM education that aims at making learners future-ready—enabling them with skills needed in the ever-changing, technology-driven, and dynamic 21st-century world.
Tekie adopts a captivating and engaging approach to learning, in line with the recommendations of the National Curriculum Framework (NCF) 2023 and NEP 2020. The curriculum is ingeniously woven into the thrilling adventures of Mel and Conji, fictional characters from the enchanting land of Avora. The Mel and Conji series epitomises a modern method of acquiring computer science knowledge and honing computational thinking skills. The program includes chapters that provide a deeper immersion in computer science that both learners and teachers may find interesting.
Tekie is a technology-empowered curriculum that encompasses the following components:
• Main Content Books: These introduce learners to the theory of computer science and computer tools. Topics in AI are also covered, along with experiential and project-based learning resources.
• Coding Books: Specifically designed to nurture coding skills, this booklet aligns with the experiential and contextual learning approach of the coding curriculum, fostering critical thinking and problemsolving abilities.
• Animated Learning Videos: The program is powered by high-quality animation-based learning videos that deliver learning in an engaging manner.
• Teacher Manual: This valuable resource supports classroom instruction, ensuring that educators effectively deliver the curriculum.
Welcome to the captivating realm of Tekie! We hope you relish this educational journey as it equips you with the tools you need to thrive in the exciting and ever-changing world of the 21st century.

Main Parts of a Computer
Our body has different parts that help us to do different things.
In the same way, a computer also has different parts. All these parts help us to work on it.
The four main parts of a computer are: monitor, CPU, keyboard, and mouse. Let us learn more about them.
Monitor
A monitor looks like a TV screen. It shows us what we are doing on a computer. We can watch videos, look at pictures, and read on it.
CPU
A CPU is known as the brain of the computer. It orders the other parts of the computer to work properly.
Keyboard
A keyboard helps us write on a computer. It has many buttons on it, known as keys. We can press them to type letters, symbols, and numbers on a computer.
Mouse
A mouse allows us point to and select different things on the monitor. When we move the mouse, a small arrow, called pointer, moves on the monitor.
Did You Know?
Do you like watching cartoons? They are created on computers. People who make cartoons on computers are called Animators.
Match the following. 1 Do It Yourself 2B
Devices
The parts of a computer are also called devices. They are of different types:
1. Input Devices: These devices help us tell the computer what to do.
Keyboard: It helps us to write on a computer.
Mouse: It helps us to select an item on the computer monitor.
2. Output Devices: These devices help the computer to share information with us by displaying the final output.
Monitor: It shows what we are writing on a computer.
Compact disc: It is a round, flat disc with a shiny surface. It can store digital data like music, movies, and software.
Speakers: It plays sounds and music for us.
3. Storage Devices: Where do you keep your things like toys, clothes, and books? You store them in a cupboard. In the same way, a computer stores information in storage devices. There are many examples for storage devices.
Printer: It prints the work we do on paper.
Pen drive: It is a small, portable, and pocket-friendly storage device. It is used to take data from one computer to another. It is also known as a flash drive.
Hard disk: It is like a box that stores all the data in the computer. Every computer needs a hard disk to remember things.
Memory card: It is used to expand the storage capacity of mobile phones, digital cameras, and similar devices.

Starting a Computer
In the previous chapter, you learned about many activities a computer can do. But to do these activities, you first need to know how to start a computer.
A computer can be started by following these simple steps:
1. Look for the main power switch. Switch it on.
2. Press the On button on the CPU.
3. Press the Power button on the monitor.
4. Once turned on, the computer takes some time before it is ready to use. Wait till the Windows screen appears.
Write T for True and F for False.
When we switch on the main power button, the Windows screen appears.
The CPU must be turned on before we switch on the monitor.
Shutting Down a Computer
Shut down means to turn your computer off. Always shut down the computer when it is not in use.
A computer can be shut down by following these steps:
1. Click Start to open the menu.
2. Then, click on the Power icon.
3. Click on the Shut down option from the second menu. The computer will start shutting down.
If you turn off the main power switch directly, the computer will turn off immediately. This is dangerous because it can:
1. damage the computer, and
2. damage the activity you were doing on the computer.
Therefore, you should always shut down the computer using the above steps.
Computers have a part called UPS. The UPS keeps the computer on even if there is no electricity. Did You Know?

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?
Types of Keys
Let us learn about the different types of keys.
Alphabet Keys

• Talking Toys: Some toys use AI to understand your voice and respond with sounds, songs, or even short sentences.
• 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.
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.
• 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, Quick, Draw!
