Warm-up

The opening five minutes — a scene that sparks curiosity

ConceptBenford's Law

Open with Benford's Law. Ask students what they notice and what question the resource raises before introducing the formal idea.

Explore

Core lesson — students manipulate, notice, and explain

ConceptStatistics and Inference

Let students explore Statistics and Inference, then ask them to describe the pattern, argument, or representation in their own words.

MathematicianCarl Friedrich Gauss

Let students explore Carl Friedrich Gauss, then ask them to describe the pattern, argument, or representation in their own words.

Extend

Extension or assignment — for students ready to go further

MathematicianPierre-Simon Laplace

Use Pierre-Simon Laplace as an extension or assignment that connects the lesson to a broader mathematical story.

ConceptBayes' Theorem

Use Bayes' Theorem as an extension or assignment that connects the lesson to a broader mathematical story.
