As a mathematician, this would be somewhat interesting material for a college History and Philosophy of Mathematics course, but in Algebra, you should just learn algebra.
Yes, the material could be interesting, but from what I've gathered from comments the curriculum is intended for a 6/7th grade algebra course. I think they would benefit more in the long run from a strong foundation rather than what he will be offering them.
