Warm-up

The opening five minutes — a scene that sparks curiosity

MathematicianArchimedes

Open with Archimedes. Ask students what they notice and what question the resource raises before introducing the formal idea.

Explore

Core lesson — students manipulate, notice, and explain

MathematicianLiu Hui

Let students explore Liu Hui, then ask them to describe the pattern, argument, or representation in their own words.

Visual geometry🥧 Area of a Circle = πr² — Unrolling Sectors into a Rectangle

Let students explore Area of a Circle = πr² — Unrolling Sectors into a Rectangle, then ask them to describe the pattern, argument, or representation in their own words.

Extend

Extension or assignment — for students ready to go further

Open problemPerfect Cuboid — Can All 7 Lengths Be Integers?

Use Perfect Cuboid — Can All 7 Lengths Be Integers? as an extension or assignment that connects the lesson to a broader mathematical story.
