A 21st-century skills playbook for the classroom

Science and maths stick when learners build them together. This library develops the 21st century skills of collaboration, communication and critical thinking through proven cooperative-learning structures, each written up with a worked Cambridge example you can run tomorrow, and every lesson pack names the one that fits its lesson. Some build the class as a team; others drive the thinking on a tricky concept.

How these lessons are built

We teach science and maths as something learners do together, not something done to them. Most lessons here are built around a cooperative-learning structure that develops the 21st century skills of collaboration and communication: a clear task, a real reason to talk, and individual accountability so every learner thinks, not just the confident few.

Structured talk also gives our many English-as-an-additional-language learners a safe route into the subject, rehearsing an idea with a partner before they have to write it. The plans pair this with active practice, quick formative checks, and grouping that lets stronger and developing learners move each other forward.
