Coding and technology · Maths CAS idea
Make maths more accessible with code
CreativityServiceProject-ready
With a teacher who supports visually impaired students, build a small tool that turns graphs into sound or describes them in text.
Where the maths comes in
Mapping values to pitch, describing shape (increasing, turning points) in words.
Which CAS strand it fits
- Creativity: The arts, and other experiences that involve creative thinking.
- Service: Unpaid, voluntary work with others that also has a learning benefit for you.
Your CAS coordinator decides how an experience counts at your school. Strand summaries are provisional (our words, being checked).
How to run it
- Learn from the teacher and the students what is hard.
- Prototype and test with the people who will use it.
- Improve it based on their feedback.
- Share the tool and instructions.
This can grow into a CAS project if your CAS coordinator agrees: see planning a maths CAS project.
How to evidence it
- Notes from the users
- Versions and test feedback
- Final tool
Date everything and keep it in your school's CAS portfolio as you go. More on what counts as evidence.
Reflection prompts
Questions to think about, not answers to copy. Write your reflections in your own words, in whatever form your school accepts.
- How did the users change what you built?
- What did you learn about accessibility?
- What would you do differently?
Learning outcomes this often gives a chance to show
- Ethics. What choice in this experience had a right and a wrong way to do it? Whose interests did you have to protect (privacy, safety, fairness), and how?
- Global significance. How does the local need you worked on connect to a wider issue? What did you learn about that issue that you did not know before?
- Collaboration. What did someone else bring that you could not have done alone? Describe a disagreement or a mix-up in the team. How was it resolved?
Whether you meet an outcome depends on what you actually do and reflect on, not on the idea. Outcome labels are our short summaries, being checked.
Safety and ethics
- Involve users as partners and respect their privacy.
