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.

Why do programs need a start or trigger?

Programs need a start or trigger so they know when to begin, for example when you click a button, press a key, or tap the screen.

How do children learn coding at KS1?

Children learn coding at KS1 by using simple commands to control actions, putting instructions in order, and testing what happens, then changing the code if it does not work.
