COMPUTER SCIENCE

Grade 1

Together We Learn and Grow

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’s in the fields of medicine, space exploration, education, science, or business, no sector remains untouched by this transformative wave. To not just survive but 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.

Recognizing this imperative, the National Education Policy of 2020 (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 Sciences, 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 epitomizes a modern method of acquiring Computer Science knowledge and honing coding skills and computational thinking.

Tekie is a technology-empowered curriculum that encompasses a few key components:

• Main Content Books: These introduce learners to the theory of computer science and the tools used in the field. Topics in AI are also covered, along with experiential and curiosity-based learning resources.

• Coding Book: Specifically designed to nurture coding skills, this booklet aligns with the experiential and contextual learning approach of the curriculum, fostering critical thinking and problem-solving 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 can 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 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.

Do It Yourself 3A

Match the following.

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. Storage devices are of different types.

Printer: It prints the work we do on paper.

Write I for input devices and O for output devices.

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!

Think and Tell

A computer needs electricity to work.

The CPU must be turned on to start the computer. The CPU is turned on when we switch on the monitor.

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.

Did You Know?

Computers these days have a part called UPS. The UPS keeps the computer on even if there is no electricity.

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?

Did You Know?

A standard keyboard has 104 keys on it.

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.

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 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.

Spacebar: The Spacebar 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 Enter.

Enter

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.
