Maths - C@S Projects

Maths C@S Projects are thematic and cover a range of topics including sleep patterns, environmental sustainability and internet access. They contain several tasks so your students can delve deep into a topic and make connections between what they learn at school and the real world. Each project can be modified to suit your needs.

In each Maths C@S Project, we’ve included a student worksheet, teacher notes and solutions, and a marking rubric. And in case your students don’t have access to computers or the internet, you can download data from our Prepared Samples.
