I have some feedback on the way in which the new practice maps are structured. I find that there is a mishmash of topics - although the topics themselves seem to be relevant.
For example: Calculus: The map starts with a skill on "identity functions". This, along with other basic skills should be taught in Algebra / Advanced Algebra.
The Combinatorics map has a large number of skills on equations and sets. While these skills may perhaps be as foundational skills, they do not belong in that map. They belong in a map on Algebra (or perhaps Miscellaneous).
Some re-organisation of skills would be highly appreciated.
