Code - An Introduction

Code is how we tell computers what to do. In this quiz, you will spot simple coding ideas like starts, actions, and instructions that make things happen on screen.

(quiz starts below)

Fascinating Fact:

Many programs start with an event, like clicking a green flag or pressing a key. The event tells the program when to begin.

In KS1 Computing, children learn that code is a set of instructions that controls what happens in a program. You might make a character move, play a sound, or change the screen by choosing simple commands and putting them in a sensible order. Programs often wait for a start signal, then follow the instructions carefully so the computer can do the same thing every time.

Key Terms

Code: Instructions that tell a computer what to do.
Command: One instruction, like move, turn, or play a sound.
Event: Something that starts an action, like a click or key press.
