These resources were created for remote use during the pandemic and are not designed for classroom teaching.
Lesson details
Key learning points
- Classification is a type of ML task where an AI system assigns data into predefined categories or "classes".
- The AI classification system is trained on labelled data.
- Classification is one of the most fundamental tasks in AI and underpins many real world systems.
Keywords
Class - a predefined group used to organise data that machine learning (ML) developers use to train classification models
Label - each piece of data is annotated with one or more labels which provide information about that data
Common misconception
A classifier can be improved by providing more training data.
More data doesn't always mean improved predictions. The quality of data provided to a classifier is as important as the quantity.

The starter quiz will activate and check your pupils' prior knowledge, with versions available both with and without answers in PDF format.
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.
