These resources will be removed by end of Summer Term 2025.
Switch to our new teaching resources now - designed by teachers and leading subject experts, and tested in classrooms.
These resources were created for remote use during the pandemic and are not designed for classroom teaching.
Lesson details
Key learning points
- Program events can be triggered when recognition points are met.
- Program flow can be changed using blocks that detect if a recognition point has been met, or by using certainty values.
Keywords
Recognition point - the level of certainty that causes an input to match a class
Program flow - the order in which a computer program executes instructions
Common misconception
Building a machine learning app just means coding as you would do with any other programming project.
Building a machine learning app involves data collection, model training and coding the application. These facets are integral in developing a machine learning app.

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.

When programmers write code, they use a special tool called an IDE (Integrated Development Environment). In an IDE, different colours are used to help programmers understand the code:
- • Blue - numbers and boolean values
- • Green - strings
- • Purple - keywords
provides a visual output
provides an audio output
checks if a class is detected with a certain level of confidence
gives a numerical value for the model's confidence
