OK, I'm being a bit silly, but there is apparently a Texas firm that publishes elementary and middle school workbooks that are written from a fundamentalist Christian point of view. It seems there may actually be a fundamentalist Christian "versions" of mathematics, biology and history.
So, is there a "Catholic Math"? (NO lisping pun intended.) I recall from my parochial school days that the Catholic Math was Algebra in the 6th grade.
Those Arabs with their zero! Seriously! I mean, it's NOT a natural number. There's a reason you can't divide by it!
We've used Seton home schooling books which approach every subject from a catholic viewpoint, including math. I didn't find any controversial issues or teachings, just good educational subjects.
I'm still trying to figure out exactly what a "catholic viewpoint" towards mathematics consists of, aside from the medieval discussion of how to determine the head of a pin angel count.
I think historical knowledge of astronomy? knowledge of historic astronomy? - an understanding of the metaphysical implications of a geocentric astronomy, as well as an understanding of "perfect" motions and "eternal" motions/bodies is necessary to understand some theological writings, or writings by some theologians (Aquinas, Augustine, Dante, others). I was lucky enough to learn these things in astronomy classes, rather than as glosses to the theology and philosophy readings. Another program could likely accomplish the same with the latter method.
Back in my parochial school days, "Catholic Math" meant Algebra in the 6th grade.
I think the way Catholics do math is in the Classic Way, or the Socratic Method. I was doing Algebra back in 6th grade to. I think most Parochial systems are based on the Socratic method.
What's the Socratic Method?
The Socratic method, if it's even real, is good for teaching logic and rhetoric. It's awful for teaching grammar. And there are grammatical elements of math (and not just the "how to write numbers are words" stuff I mentioned in Christian Men). Certainly algebra can't be taught to 6th graders Socratically. I could hardly learn algebra Socratically as a college junior.
I transfered to the public system for the sixth grade onwards (talk about a culture shock!). So I got taught "The New Math", in the time honored American system of "The teacher is one chapter ahead of the students in the book".
However, having seen some of the algebra homework done by older kids, it appears that the parochial school algebra class required "classical proofs" of your solutions, similar to what I did in High School Geometry class.
Well, ya know, dem Catholics is great at multiplyin'!
Catholic Math 1+1+1=x; x = 3 for all sets except God. In the God set x=1.
