a named piece of data stored in a computer’s memory which can be accessed and changed by a computer program

a symbol or word that instructs the computer to perform a specific calculation or action

a sequence of characters, e.g. letters, numbers, spaces, and other symbols

a whole number that can be positive, negative, or zero

Working with numerical inputs

Computing

Writing a text-based program

Using selection

Selection with multiple paths

Iteration using while loops

Building a program using control structures

This unit introduces pupils to text-based programming with Python. Pupils start with programs involving input and output, and gradually move on to using arithmetic operations, randomness, selection, and iteration. Pupils will consolidate these skills in a project at the end of the unit.
