Concentric Circles is a differentiation technique which moves students up and down the ladder of abstraction, applying a single idea in multiple contexts.
In this example, my students are applying the big idea “🏛️ Problems lead to new rules. Those rules lead to new problems.” (yes, it’s a favorite of mine) to three contexts of increasing “size”: home, school, and our city.
You could add to or change those around, of course. The key is how students are thinking! They’re seeing how one idea can apply similarly or differently across various contexts.
