Re: [isabelle] Isabelle (or something else) for Highscool Kids

In my opinion, pure predicate logic will come across as boring and dry. The most understandable problems would be puzzles in propositional logic, for which SAT solvers are much more appropriate than any interactive tool.

I suggest something from recreational mathematics, such as Fibonacci numbers and basic facts about them. If these students are familiar with induction, then you could prove some simple facts about the Fibonacci numbers. Possible alternatives include the GCD function and Ackermannâs function.

An alternative might be to teach a tiny bit of functional programming, along with proofs.

In both cases, you may be able to get away with equational logic, especially through the magic of assumes/shows.
