Computer Coding for kidsComputer coding for kids in Primary School. Homework help with computers and computer coding languages in Key Stage 1 and Key Stage 2. Learn algorithms, simple programming and coding.

What is a computer?

A computer is a machine. A computer doesn’t have a brain and can’t think for it’s self. Instead it has a set of instructions it follows so that it is able to do clever things. 

Computers are everywhere. They help us do many useful things. Computers are used in schools for learning, at the doctors to keep track of appointments and at home too. But did you know that your microwave has a computer? When you press the buttons to cook your food a tiny computer built inside knows how to cook the food by the order you press the buttons. Clever right? It’s the same with your washing machine, dishwasher and your camera.

What is computer coding?

Computer coding is a list of instructions a computer follows to get a job done. This is also called an algorithm, the steps it need to take to complete a task.

The internet

The internet is loads of computers all connected together around the world. The computer that has this website on is in the the United Kingdom. In a split second you can click on other website and look at a website on a computer in China. Cool! You can use computers, tables, mobile phones and even your TV to see the internet. 

Staying safe on the internet

It is really important to stay safe on the internet. This means not sharing your personal information like your phone number, address and full name with anyone that you may meet on the internet. Check out our Internet Safety page for more information.

Input and output devices

An input device is something that sends information to a computer, this could be a webcam, microphone or a keyboard.

An output device is something that computer sends out. A computer could send an image to be printed to a printer, or it could produce a sound that would come out of its speakers.

How to create an algorithm that works

We already know that an algorithm is a list of instructions that a computer follows. So lets look at how we would write these instructions.

Imagine you are writing instructions to tell an alien how to walk from your bedroom to your bathroom. What would this look like?

  1. Walk forward out of the bedroom.
  2. Turn left.
  3. Walk forward
  4. Turn right.
  5. Walk forward into the kitchen.

That’s a start but what happens if the bathroom door is shut? How would the alien know what to do? Okay lets try again…

  1. Walk forward out of the bedroom.
  2. Turn left.
  3. Walk forward
  4. Turn right.
  5. Check bathroom door
    1. If it is closed, open it.
    2. If it is open, do nothing.
  6. Walk forward into the bathroom.

That’s better, but what if the cat gets in the way, or someone is in the bathroom?

When you write code you have to think of everything that could happen and test your code. If you get an error you need to debug the code and fix the error.

Create your own code

People who create computer code are called coders. There are many programming languages you can learn to use. For example, C, Java, Ruby, JavaScript and Python. If you have never done any programming before then it’s best to start with Scratch. It’s an easy way to learn how code works without having to know all the code words.

Learn to type

Want to learn to type fast? Then learn to touch type. Being able to touch type means that you don’t have to look at the keyboard while you are typing. It will make you faster as you will then be able to keep your eyes on the text you are copying and not keep having to look at the keyboard. It may be slow to start with, but trust me it’s worth learning.
