Lesson 4 - Starting with selection
In this lesson, pupils develop their understanding of how the flow of actions in algorithms and programs can be controlled by conditions. They are introduced to selection, and learn to represent conditions and actions using the If… Then… structure. They apply their understanding by using selection in an algorithm created to achieve the requirements of a task. They discover that infinite repetition is required when programming input devices to repeatedly check if a condition has been met.
- To explain that a loop can be used to repeatedly check whether a condition has been met
- I can explain that a condition being met can start an action
- I can identify a condition and an action in my project
- I can use selection (an ‘if…then…’ statement) to direct the flow of a program
