I can help you with pedagogical math checking.
“Orientation” is a technical mathematical term. I think “position” would be what’s wanted here.
It’s not the sequence that’s recursive, but rather a way of describing it.
The “story line” of this activity isn’t nearly so clear to me as in previous activities….
The first part of this sentence is crucial, yet it might get lost because it’s part of an “if” clause. “The key is to assume…” might be a good way to set it off. In fact, the assumption might be indicated on a graph, for visual learners.
May I help you? Contact me.

What is pedagogical math checking? It includes checking for mathematical correctness, based on knowledge of mathematics from my extensive graduate work in the field. But it’s much more: I can also check the pedagogical approach and recommend improvements, drawn from my extensive teaching experience and a PhD in mathematics education.
