"Tech tree" of elementary school math topics?

Hello, I have a seven-year-old son (has mastered arithmetic operations) that I'll be doing a little homeschooling with. I was wondering if anyone had already worked out a directed acyclic graph of elementary school math topics that illustrated which topics had which other topics as prerequisites. This would help him/us plan out some paths through the "tech tree". Does this graph already exist somewhere?

Though not only for Elementary School, Khan Academy has developed a graph pertaining to all their topics on Math. It can be found in here: https://www.khanacademy.org/exercisedashboard

Place value. Times tables

Everything else.

A “tech tree” is a little simplistic in my experience. You could check out the Khan Academy option for that.

But in reality, the topics interweave a lot and layer on top of each other and there’s not a single correct order.

For more detail, try https://achievethecore.org/coherence-map/ (although this is aimed at educators more)
