@foldworks I've been thinking about the early childhood math curriculum since, well, I was a early child myself.
My idea is to introduce the Stern-Brocot tree, the Symmetry Group of the Square, Pascal's Triangle, and computer programming to youngsters.
These are all incredibly fertile concepts that set up future lessons about mathematics, in lessons that are likely appropriate for children, others that are more likely to be appropriate for teens, and even others that are more likely to be appropriate for undergraduate or even graduate students.
I am very keen on finding concepts that meaningfully connect to advanced research-level mathematics, but are also approachable by the youngest children.
