Lesson 2
Using variables in programs
Introduction
Pupils apply their understanding of variables to record star-jumps and write an algorithm to represent this. They explore a program using variables and debug it so the BBC micro:bit can be used to record an activity.
Learning objectives
- To write algorithms that use variables
- To explain how variables are used in programs
- To debug programs containing variables
