Playing with Dominos: Proof by Induction

  • Playing with Dominos: Proof by Induction

    Gail Kaplan
    A hands-on approach to learning proofs by induction. Students create patterns of dominos so that when the first domino is pushed, the entire design collapses, one domino at a time. Students then build designs that do not work. By constructing a list of conditions that ensure a given pattern will collapse, students discover the basis for proofs by induction. A discovery worksheet leads students through mathematical examples.
