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.

Mapping of Tools and Technologies Across Grades
The curriculum is thoughtfully mapped to introduce tools and technologies at each grade level, ensuring a smooth and progressive learning experience for students. Beginning with basic concepts in junior grades, the curriculum gradually incorporates more advanced tools and concepts in higher grades. This structured approach enables students to build on their knowledge each year, equipping them with essential skills in computer science and technology as they progress from grade 1 through grade 8. By the time they reach the higher grades, students are well-equipped to tackle complex projects, think critically, and apply their skills in real-world scenarios. The curriculum not only fosters technical proficiency but also encourages creativity, problem-solving, and a deeper understanding of the digital world.

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 like 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, words, and numbers on a computer.
Mouse
When we move the mouse, a small arrow moves on the monitor. We can use this small arrow to select different things on the monitor.
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.
Monitor: It shows what we are writing on a computer.
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.
Write I for input devices and O for output devices.
Hello my friend, how are you? I miss you.
A computer has four main parts: monitor, CPU, keyboard, and mouse.
a We can see on the monitor what we are doing on the computer.
b The CPU is like the brain of the computer.
c The keyboard helps us to type letters, words, and numbers on a computer.
d The mouse helps us to select things on the monitor.

Starting 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. We can now start using the computer! What will happen if we just switch on the main power and then turn on the monitor? Will the computer start?
Write T for True and F for False.
Shutting Down a Computer
To shut down your computer means to turn it 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 these days 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 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?
Now, 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. We can use these keys to type words and sentences on a computer.
Alphabet keys

Arrow Keys
We have four arrow keys: up arrow key, down arrow key, right arrow key, and left arrow key.
We use the left arrow key to move the cursor left.
We use the right arrow key to move the cursor right.
We use the up arrow key to move the cursor up.
We use the down arrow key to move the cursor down.
Special Keys
There are some special keys on a keyboard. Let us learn about them.

Introduction to AI
Robots work on artificial intelligence, or AI.
Humans can do many things. They can talk to each other. They can answer questions. They can do things that they are told to do. They can do things on their own, too. Humans are intelligent.
Similarly, some machines can also do these things. They can talk to us. They can solve problems for us. This makes these machines intelligent too.
But remember, machines are human-made. So this type of intelligence is also human-made. This type of human-made intelligence is called artificial intelligence, or AI.
AI helps some robots to walk on their own. AI also helps some robots to talk to us.
