Outcomes from selection statements
Lesson details
Learning outcome
I can explain that a conditional statement can connect a condition to an outcome.
Key learning points
- Conditions can be used in an infinite loop to check a condition.
- The condition and outcomes in an "if... then... else..." statement can be identified.
- A program can use selection to produce different outcomes.
Keywords
Repetition - part of a program where one or more commands are run multiple times in a loop
Infinite loop - a chunk of code that runs a section of the program continuously
Outcome - the actions that come from a condition being True or False
Common misconception
A condition will keep being checked on its own.
Conditions need to be inside forever loops if you want them to be repeatedly checked.
Teacher tip
Model how the "if� then� else�" structure allows a program to choose between two outcomes depending on whether the condition is true or false.
Equipment
Pupils will need access to a device with block-based programming software. Examples in this lesson use Scratch https://oak.link/scratch

We use learning cycles to break down learning into key concepts or ideas linked to the learning outcome. Each learning cycle features explanations with checks for understanding and practice tasks with feedback. All of this is found in our slide decks, ready for you to download and edit. The practice tasks are also available as printable worksheets and some lessons have additional materials with extra material you might need for teaching the lesson.
The assessment exit quiz will test your pupils' understanding of the key learning points.
Our video is a tool for planning, showing how other teachers might teach the lesson, offering helpful tips, modelled explanations and inspiration for your own delivery in the classroom. Plus, you can set it as homework or revision for pupils and keep their learning on track by sharing an online pupil version of this lesson.
