The birthday paradox is fun and easy to explain https://en.m.wikipedia.org/wiki/Birthday_problem
That a US state attempted to legislate a specific value for the number Pi and its possible consequences is also hilarious https://en.m.wikipedia.org/wiki/Indiana_pi_bill and gives itself to quite the discussion.
That a math theorem was proven by a US congressman, James Garfield, over a century ago https://en.m.wikipedia.org/wiki/Garfield's_proof_of_the_Pythagorean_theorem makes for another good discussion: it’s the Pythagoras theorem (and the proof is intuitive and easy to explain by drawing and measuring areas of triangles), and sets a baseline of expectations for the intellectual capabilities of anyone running for office … or it should.
@albertcardona so much good in here. And these are quick kids -- I think the multiple layers of ridiculousness in the attempted legislation of pi would not be lost on them!
